A Temperature Compensator Crystal Oscillator or a TCXO is a crystal oscillator that is designed to withstand high-temperature conditions. In a regular crystal oscillator the oscillation frequency fluctuates with the rise in temperature. The consequence of this is an unstable oscillation frequency. TCXO supports a stable oscillation frequency at high temperatures. For this, they take the help of a temperature compensation network which balances out the oscillation frequency at higher temperatures.

 

Performance figure of TCXO

Some of the most important performance figures of TCXO are as follows:

  • Power Dissipation – The dissipation of power in a TCXO will be much greater as compared to an ordinary oscillator keeping in view of the additional circuitry needed. In addition to that the cost becomes greater. It should also be kept in mind that the cost is greater. It is also worth remembering that it will take a short period after start-up for the oscillator to stabilize. This might be of the order 100 ms, or conceivably more, subordinate upon the plan.

 

  • TCXO PPM performance – As said earlier, the performance of TCXO temperature is much better as compared to a normal crystal oscillator. Ordinarily, figures of somewhere in the range of 10 and 40 times improvement can regularly be seen. Figures that are better than +1.5 (or -1.5) ppm over a temperature range of 0 to 70 degrees Celsius are much harder to achieve as they at that point fall into a high exactness classification where costs increment essentially.

 

  • TCXO package – TCXOs can be supplied in several packages depending upon the requirements of the end-user as well as the way they have been designed. The most well-known type of development is to build the circuit on a little printed circuit board that can be housed in a plat metal bundle. This is then reasonable for mounting onto the fundamental circuit leading body of the general hardware. As the crystal is sealed itself, this implies fixing of the general TCXO bundle isn't basic, or even required for most applications.

 

  • Output format and level - With numerous TCXOs being utilized for driving advanced circuits, a large portion of the little oscillator bundles produce what is named a clipped sine wave. This is suitable for driving a logic circuit, but in many instances it is recommended to put it through a logic buffer to make sure that it is sufficiently square. The output is generally an open collector circuit. On the off chance that a sine wave output is needed, at that point this must be picked at the start and it will confine the decision accessible.

 

  • Power Requirements – The actual requirement of power depends on the particular device. Many works from provisions of 3 V, and may draw as meager as 2 mA, even though this will rely on the general kind, the producer and the specific gadget picked.

A crystal oscillator is said to be an electrical oscillator circuit that utilizes the mechanical resonance of a vibrating crystal made up of piezoelectric material to establish an electrical signal with an exact frequency. This frequency is found to be useful in providing a stable clock signal in digital integrated circuits, keeping a track of time (in quartz wristwatches), and to settle frequencies for radio receiver and transmitters. The most widely recognized kind of piezoelectric resonator utilized is the quartz crystals, so oscillator circuits consolidating them got known as crystal oscillators, but other piezoelectric materials including polycrystalline ceramics are utilized in comparable circuits.

A crystal oscillator, particularly that utilizes quartz crystal, works by mutilating the crystal by an electric field when a potential difference is applied to the electrode. This property is known as inverse piezoelectricity or electrostriction. As soon as the electric field is taken off, the quartz that is oscillating at a precise frequency returns to its previous shape and generates an electric field. This can even set up a voltage. The consequence is that this quartz crystal starts to act like an RLC circuit but with a much higher value of Q.

Quartz crystals are produced for frequencies ranging from a few tens of Kilo Hertz to hundreds of MegaHertz. It is estimated that more than 2 Billion crystals are produced per year. Most of them have found their use in consumer devices like clocks, computers, wristwatches, cellphones, and radios. These crystals are also used inside measuring and texting equipment like oscilloscopes, signal generators, counters, etc.

 

Operation

A crystal is defined as that solid where all its constituent atoms, ions, or molecules are packed in regular order, repeated pattern in all its 3 dimensions.

Whenever a crystal made up of quartz is cut and mounted properly, it very well may be made to contort in an electric field by applying a voltage to a terminal close or on the crystal. As said earlier, this property is known as Electrostriction. When the field is removed, it sets up an electric field as it gets back in its initial shape. Thus, it behaves like an RLC circuit, made up of a capacitor, resistor, and an inductor.

One more advantage of quartz is that its size and elastic constants change in such a manner that the frequency reliance on temperature can be extremely low. The specific characteristic depends on two things: the angle at which the quartz is cut (with respect to its crystallographic axes) and the mode of vibration. As a result, the resonant frequency of the plate (depending on size) does not vary much. This conveys that a quartz filter, oscillator, or a clock remains accurate. For basic applications, the quartz oscillator is mounted in a temperature-controlled holder known as Crystal Oven. It can also be mounted on shock absorbers to forestall irritation by outer mechanical vibrations.

A temperature-controlled chamber utilized in maintaining the quartz crystal present in the electronic crystal oscillators (at constant temperature) is known as a crystal oven. Its main aim is to cease any changes in the frequency because of varieties in encompassing temperature. An oscillator of this category is known as Oven-Controlled Crystal Oscillator (OCXO; Here “XO” is an old short form for “crystal oscillator”). This kind of oscillator gets the greatest frequency stability possible using a crystal. They are used generally to manage the frequency of cellular base stations, radio transmitters, equipment for military communications as well as in measuring frequency precisely.

 

Description

Quartz crystals have found its wide use in electronic oscillators to manage the frequency generated precisely. The frequency of vibration of a quartz crystal resonator depends completely on its dimensions. When there is a change in temperature, it leads to the thermal expansion of the resonator. This results in the change of frequency of the signal produced. The coefficient of thermal expansion is very low in quartz, still, the change in temperature is the major cause of the difference in frequency in the oscillator.

The oven comes with the crystal and some electrical heating elements. It is also thermally insulated. Other electrical equipments present inside the circuit are likewise helpless against temperature float, thus, the whole oscillator circuit is enclosed inside the oven. A thermistor temperature sensor in a closed-loop control circuit is utilized to make sure that the oven is kept at a desired precise temperature as well as to manage the power of the heater. The oven is said to start its work above ambient temperature and because of it the oscillator generally requires a warm-up time after the power is supplied to reach its operating temperature. The frequency will not have the full rated stability during this warm up time.

The operating temperature chosen for the oven is that at which the slope of Crystal’s Frequency Vs. The temperature curve is Zero. SC-cut (Stress-Compensated) or AT- crystals are utilized. The SC-cut has a wide range of temperatures over which the near-zero temperature coefficient is accomplished and along these lines lessens warmup time. Instead of resistance heating elements, power transistors are used for the heaters. The power output of these transistors is not proportional to the square of the current but only to the current. This linearizes the gain of the control loop.

One of the temperatures which is common for a crystal is 75 degree Celsius. But depending on the setup it may vary between 30 to 80 degrees Celsius.

Most standard commercial crystals are indicated to an ecological temperature of 0 to 70 degrees Celsius and the industrial ones are generally specified to -40 to +85 degrees Celsius.

A ferrite choke or a ferrite bead is a piece of passive electric equipment whose role is to suppress high-frequency noise generated from electronic circuits. It is a particular kind of electronic choke. Ferrite beads provide a high-frequency current dissolution in a ferrite ceramic to create high-frequency noise subduing devices. Ferrite beads might also be known as cores, EMI filters, rings or blocks.

Ferrite beads stop Electromagnetic Interference (EMI) in two directions: either to a device or from a device. The conductive cable present in it behaves like an antenna. If the device generates radio-frequency energy then it can be easily transmitted through the cable which behaves like an unintentional radiator. Here the bead is needed for regulatory compliance just to drop EMI. On the other hand, if there are different sources of EMI (say any household appliance), then the bead will act as a barrier for the cable to behave like an antenna. This is generally common for medical equipment as well as data cables.

Generally, large ferrite beads can be found on external cabling. Several small ferrite beads are utilized in electric circuits like conductors or even around the pins of smaller circuit boards, like connectors, integrated circuits, and transistors.

 

Theory of Operation

Ferrite beads also help in passive low pass filter, by converting RF energy to heat. The electromagnetic properties and the geometry of wires coiled around ferrite beads lead to the impedance for signals having a high frequency, lessening high-recurrence RFI/EMI electronic commotion. The energy is either dissipated as low-level heat or is reflected up the cable. Just in extraordinary cases is the warmth perceptible.

It is observed that a pure inductor doesn't scatter energy however it produces reactance that prevents the flowing of signals of higher frequency. This is generally known as impedance, however, it can be any combination of reactance and resistance.

A ferrite bead or core can be summed with an inductor to improve its functionality to block undesirable high recurrence commotion. Firstly, the inductance and the reactance is increased because of the increase in the concentration of the magnetic field. Secondly, if the ferrite is so planned, it can deliver an extra loss in the form of resistance in the ferrite itself. It makes up an inductor with a very low Q factor value. This loss warms the ferrite, ordinarily by an insignificant sum. It is observed that though the signal level is much larger to result in any interference or undesirable effects in sensitive circuits, the energy blocked is commonly very little. Contingent upon the application, the resistive loss characteristic for the ferrite could be wanted.

A design that takes the help of ferrite bead to improve the filtering of noise must consider explicit circuit features and the recurrence range to block. Ferrite made up of different materials have different properties w.r.t frequency.

A tantalum electrolytic capacitor is one of the passive components of an electronic circuit. It comprises of a pellet of permeable metals of tantalum (anode) which is covered all around by an insulating oxide layer forming the dielectric. It is covered solid or even liquid electrolytes (cathode). The tantalum capacitor has a very thin and comparatively high permittivity dielectric layer and because of this, it is much better than other capacitors in having high Capacitance/Volume as well as lower weight.

Tantalum is known to be a conflict mineral. The Tantalum Electrolytic Capacitors are found to be more costly than the Aluminum Electrolytic Capacitors.

Tantalum capacitors are intrinsically polarized segments. If the reverse voltage is applied then the capacitors may get destroyed. Bipolar or Non-polar Tantalum Capacitors can be made by adequately interfacing two capacitors which are polarized in series, with the anode having an orientation in the opposite direction.

 

Basic Construction of Solid Tantalum Electrolytic Capacitors

A Tantalum Capacitor is basically a chip capacitor which consists of tantalum powder pressed and compacted into a pellet and forms the anode of the capacitors. The oxide layer of tantalum pentoxide forms the dielectric and the cathode is a solid manganese dioxide electrolyte.

 

                                                                                                        

Types of Tantalum Capacitors

The Tantalum Electrolytic Capacitors are made up in 3 different styles:

  • Axial Leaded Tantalum Capacitors – This kind of capacitor is generally used in medical, space and military applications.
  • Tantalum “pearls” single-ended style (resin-dipped) used for PCB mounting.
  • Tantalum Chip Capacitors – It has an SMD style and is used for surface mounting. Eighty percent of all Tantalum Capacitors are SMDs.

 

Chip Capacitors

As said above, more than eighty percent of Tantalum Electrolytic Capacitors are made in SMD style as Tantalum Chip Capacitors. The end faces consist of contact surfaces, furthermore, is fabricated in various sizes. One can identify different sizes using case code letters. For some of them which have been fabricated for a long time, the measurements and case coding overall makes are still to a great extent equivalent. But due to the new features of Tantalum Electrolytic Capacitors, like the “face down” technique to decrease inductance and the multi-anode technique to decrease the ESR has resulted in a much broader range of chip sizes and case codes. These takeoffs from EIA benchmarks mean gadgets from various producers are never again constantly uniform.

 

Wet Tantalum Capacitors

One of the main characteristics of the modern days Wet (non-solid) Tantalum Electrolytic Capacitor is the energy density they have as compared to the Wet Aluminum Electrolytic Capacitors and Solid Tantalum Capacitors. The self-healing property in them enables the formation of dielectric thickness with a much lower safety margin. In addition to that, Wet Tantalum Capacitors can be operated at an excess voltage from 100 V to 630 V. Apart from that it has the lowest leakage current and a relatively low ESR than all other electrolytic capacitors.

An ultracapacitor or a supercapacitor is a type of capacitor that has a much higher capacitance value than any other capacitor. However, the voltage limits of these capacitors are quite low, which shortens the distance between rechargeable batteries and electrolytic capacitors. It is to be noted that the supercapacitors can store twenty to a hundred times more energy per unit mass or volume than electrolytic capacitors. It has also got a feature of delivering and accepting charge in a much faster manner than batteries. In addition to that, it can withstand several other discharge cycles and charge than rechargeable batteries.

 Supercapacitors have found its uses mainly in those applications that need rapid charge or discharge cycles, instead of long period smaller vitality stockpiling – in trains, automobiles, cranes, elevators, and buses, where they are utilized for energy storage for short term, boost mode power delivery or for regenerative braking. Smaller units of supercapacitors are used in the backup of memory for SRAM (Static Random Access Memory).

In contrast with ordinary capacitors, supercapacitors do not take the help of conventional solid dielectric, but, they utilize electrochemical pseudocapacitance as well as electrostatic double-layer capacitance. The two of which add to the net capacitance of the capacitor, with some differences:

  • Electrochemical pseudocapacitors – It uses conducting polymer or metal oxide electrodes having a large value of electrochemical pseudocapacitance in addition to the double-layer capacitance. Pseudocapacitance can be achieved by Faradaic electron charge transfer with intercalation, electrosorption or redox reactions.
  • Electrostatic double-layer capacitors (EDLCs) – utilizes carbon electrodes having a much higher value of double-layer capacitance than electrochemical pseudocapacitance, accomplishing division of charge in a Helmholtz double layer at the interface between the electrolyte and the conductive electrode’s surface. The charge separation is of the order of angstroms (0.3 to 0.8nm). This value is much smaller than that of a conventional capacitor.
  • Hybrid capacitors, like the lithium-ion capacitor, take the help of electrodes that come with different characteristics: one showing up mostly the electrochemical capacitance while the other showing up mostly the electrostatic capacitance.

An ionic conductive connection is formed by the electrolyte between both the electrodes which separates them from capacitors with conventional electrolytes (dielectric layer always exists), and the purported electrolyte, e.g., MnO2 or conducting polymer. These capacitors are polarized by design with symmetric electrodes, or, asymmetric electrodes, by a potential applied during its manufacture.

 

Basic Design

Supercapacitors come with 2 electrodes which are separated by an ion-permeable membrane, as well as by an electrolyte ionically summing both electrodes. Whenever a voltage is applied to the electrodes, it gets polarized and thus, the ions present in the electrolyte form an electric double layer of polarity that is opposite to that of the electrode.

Polymer film capacitors, or film dielectric capacitors or plastic film capacitors or film capacitors are generally known as power film capacitors and "film caps". These are those electrical capacitors having an insulating plastic film (dielectric).

Depending on the needed dielectric strength, the dielectric films are drawn into a much thinner thickness and are then offered with electrodes. The electrodes used in these capacitors might be metalized zinc or aluminum applied legitimately to the plastic film’s surface, or a different metallic foil. 2 of the conductive layers are winded in a cylindrical shape, generally flattened to decrease the requirement of mounting space on a printed circuit board. They may be also stacked as multiple layers to form the body of a capacitor. Along with electrolytic capacitors and ceramic capacitors, film capacitors are the most popular and common capacitors type for utilizing electrical equipment. They are utilized in several DC and AC electronics and microelectronics circuits.

Though the constructions and materials utilized for larger power film capacitors are very much the same as that of ordinary film capacitors, capacitors coming with a very high rating of power for power system applications and electrical installations are often categorized separately due to some historical reasons. Today several modern electronic equipment have got the ability to manage the level of high powers that was earlier one of the biggest constraints of components related to "electrical power". The difference between "electrical" and "electronic" rating of power has become less distinct. In the earlier time, the line of boundary between these two families was approximately 200 Volt-Ampere but the modern ones are well made to manage high power levels.

Example manufacturing process

The example discussed below describes a common assembling process stream for wound metalized plastic film capacitors.

  • Metallization and Film stretching – To uplift the value of capacitance of the capacitor, the plastic film is drawn utilizing an exceptional expulsion procedure of bi-pivotal extending in transverse and longitudinal direction.
  • Film slitting - The mother folds are cut into little portions of plastic film in the necessary width.
  • Winding – 2 films are then made to roll together into a cylindrical winding.
  • Flattening – The winding is then generally flattened into the shape of an oval by utilizing mechanical pressure.
  • Application of Metallic Contact layer – A liquefied contact metal like zinc or tin is used to cover up the projecting end electrodes.
  • Healing – Healing is done by applying an absolutely adjusted voltage over the electrodes of the winding with the goal that any current deformities will be "consumed with extreme heat".
  • Impregnation – For protection from moisture, the winding is made to impregnate using silicone oil (insulating fluid).
  • Attachment of terminals – The capacitor’s terminals are welded on the end metal contact layers.
  • Coating – Succeeding the attachment, the body of the capacitors is dunked into a protective coating.
  • Electrical final test – Before the use of every capacitor it is important to test it for the desired parameters, like, Impedance, Capacitance or dissipation factor.

A ceramic capacitor is regarded as the fixed value capacitor where the dielectric is a ceramic material. It is made up of alternating 2 or more layers of ceramic as well as a layer of metal that behaves like an electrode. The piece of the ceramic material characterizes electrical conduct and consequently applications. Ceramic capacitors can be categorized into 2 application classes:

  • Class 1 Ceramic Capacitors – This type of ceramic capacitors provide low losses and high stability for resonant circuit applications.
  • Class 2 Ceramic Capacitors – It provides high volumetric efficiency for coupling, by-pass, and buffer applications.

Ceramic capacitors mostly the Multilayer Ceramic Capacitors - MLCC are one of that electrical equipment that is the most used ones. They are available in different sizes and shapes and are utilized in capacitors for EMI / RFI suppression, power capacitors for transmitters and as feed-through capacitors.

 

MLCC

An MLCC or Multi-Layered Ceramic Capacitors comes with several separate capacitors that are grouped together in parallel and are contacted using the terminal surface. The materials used for making MLCC chips are a mixture of ferroelectric or paraelectric (finely ground granules) with some precisely decided added substances. Both of them are mixed together to form a homogeneous mixture. The size of the powder as well as the composition of the mixture (small as 10nm) shows the expertise of the manufacturer.

                                                            

A thin foil of ceramic is cast from a suspension of the powder with an appropriate binder. This ceramic foil is then rolled up for transport. It is then unrolled. After this, they are divided into sheets of equal size which are screen printed using a paste of metal. Now, these sheets are our electrodes. These sheets are grouped together in layers and pressure is applied which can be solidified on the application of pressure in an automated process. Along with the relative permittivity, the number and size of the layers help in deciding the value of capacitance. The electrodes are grouped in an alternate arrangement somewhat balanced from the abutting layers with the goal that they each can later be associated on the offset side, one right, one left. The stack that is layered is cut into small individual components. High mechanical exactness is required.

After the cutting process is over, the binder is worn out of the stack. This is trailed by sintering at temperatures somewhere in the range of 1,200 and 1,450 °C creating the last, essentially crystalline, structure. The burning process then makes up the needed dielectric properties. Cleaning and metallization are succeeded in the burning process. With the help of the metallization process, the inner and the ends electrodes get connected in parallel and the terminal is provided to the capacitor. At last, a 100% estimating of the electrical qualities will be finished.

A ceramic capacitor is regarded as the fixed value capacitor where the dielectric is a ceramic material. It is made up of alternating 2 or more layers of ceramic as well as a layer of metal that behaves like an electrode. The piece of the ceramic material characterizes electrical conduct and consequently applications. Ceramic capacitors can be categorized into 2 application classes:

  • Class 1 Ceramic Capacitors – This type of ceramic capacitors provide low losses and high stability for resonant circuit applications.
  • Class 2 Ceramic Capacitors – It provides high volumetric efficiency for coupling, by-pass, and buffer applications.

Ceramic capacitors are one of that electrical equipment that is the most used ones. They are available in different sizes and shapes and are utilized in capacitors for EMI / RFI suppression, power capacitors for transmitters and as feed-through capacitors.

 

Application Classes – Definitions

The distinctive ceramic materials utilized for making ceramic capacitors like ferroelectric or paraelectric ceramics impacts the electrical attributes of the capacitors. Utilizing the mixture of paraelectric substance that is in light of titanium dioxide brings about entirely steady and linear capacitance value within a pre-defined range of temperature and low losses at high frequencies. The mixture as said above has a low value of permittivity such that the capacitance of these capacitors is generally less.

To get a high value of capacitance in ceramic capacitors, a mixture of ferroelectric materials, like barium titanate, and its specific oxides should be used. The permittivity value of this dielectric material is much higher but the capacitance is non-linear over the range of temperature, and the loss at high frequency is much higher. These features of ceramic capacitors need to be grouped into "application classes". Let's have a look at each of them.

  • Class 1 Ceramic Capacitors – Class 1 Ceramic Capacitors are much accurate and temperature-redressing capacitors. They provide the most steady and stable temperature, voltage as well as frequency to some extent. Because they have low losses, they are generally suitable for resonant circuit applications. The fundamental materials required for making Class 1 Ceramic Capacitors consist of paraelectric materials (finely ground granules) like TiO2 (Titanium Dioxide) altered by added substances of Zirconium, Tantalum, Niobium, Zinc, Strontium, Cobalt and Magnesium. All of these are important to get the desired linear characteristics of the capacitors.

 

  • Class 2 Ceramic Capacitors – Class 2 Ceramic Capacitors have a high permittivity along with a dielectric and because of this, it has a much better volumetric efficiency than Class 1 Capacitors. But still, it has lower stability and accuracy than the Class 1 Capacitors. The ceramic dielectric is described by a nonlinear difference in capacitance over the temperature run. The capacitance value of the capacitor also relies on the applied voltage. They are good for coupling, decoupling and bypass applications.
