5 Electronic component - Transistors 1 JFET (Junction Field-Effect Transistor) – N-CHANNEL or P-CHANNEL https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

7 Semiconductor device - Transistor 1 The field may be applied by a reverse- biased p–n junction, forming a junction field-effect transistor (JFET) or by an electrode isolated from the bulk material by an oxide layer, forming a metal–oxide– semiconductor field-effect transistor (MOSFET). https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

8 Transistor 1 Structure: BJT, JFET, IGFET (MOSFET), insulated- gate bipolar transistor, "other types" https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

9 Transistor 1 Functionally, this makes the n-channel JFET the solid-state equivalent of the vacuum tube triode which, similarly, forms a diode between its grid and cathode https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

10 Transistor 1 Metal–semiconductor FETs (MESFETs) are JFETs in which the reverse biased p–n junction is replaced by a metal– semiconductor junction. These, and the HEMTs (high-electron-mobility transistors, or HFETs), in which a two-dimensional electron gas with very high carrier mobility is used for charge transport, are especially suitable for use at very high frequencies (microwave frequencies; several GHz). https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

11 Transistor 1 Unlike bipolar transistors, FETs do not inherently amplify a photocurrent. Nevertheless, there are ways to use them, especially JFETs, as light-sensitive devices, by exploiting the photocurrents in channel–gate or channel–body junctions. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

12 Transistor 1 Nearly all JFETs are depletion-mode because the diode junctions would forward bias and conduct if they were enhancement-mode devices; most IGFETs are enhancement-mode types. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

13 Transistor 1 JFET, where the gate is insulated by a reverse-biased p–n junction https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

14 Transistor 1 MESFET, similar to JFET with a Schottky junction instead of a p– n junction https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

15 JFET 1 The junction gate field-effect transistor (JFET or JUGFET) is the simplest type of field-effect transistor. It can be used as an electronically- controlled switch or as a voltage-controlled resistance. Electric charge flows through a semiconducting channel between "source" and "drain" terminals. By applying a reverse bias voltage to a "gate" terminal, the channel is "pinched", so that the electric current is impeded or switched off completely. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

16 JFET - Structure 1 The JFET is a long channel of semiconductor material, doped to contain an abundance of positive charge carriers or holes (p-type), or of negative carriers or electrons (n-type). Ohmic contacts at each end form the source (S) and drain (D). A pn-junction is formed on one or both sides of the channel, or surrounding it, using a region with doping opposite to that of the channel, and biased using an ohmic gate contact (G). https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

17 JFET - Function 1 JFET operation is like that of a garden hose. The flow of water through a hose can be controlled by squeezing it to reduce the cross section; the flow of electric charge through a JFET is controlled by constricting the current- carrying channel. The current also depends on the electric field between source and drain (analogous to the difference in pressure on either end of the hose). https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

18 JFET - Function 1 Some JFET devices are symmetrical with respect to the source and drain. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

19 JFET - Schematic symbols 1 The JFET gate is sometimes drawn in the middle of the channel (instead of at the drain or source electrode as in these examples). This symmetry suggests that "drain" and "source" are interchangeable, so the symbol should be used only for those JFETs where they are indeed interchangeable. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

20 JFET - Comparison with other transistors 1 At room temperature, JFET gate current (the reverse leakage of the gate-to-channel junction) is comparable to that of a MOSFET (which has insulating oxide between gate and channel), but much less than the base current of a bipolar junction transistor. The JFET has higher transconductance than the MOSFET, as well as lower flicker noise, and is therefore used in some low-noise, high input-impedance op-amps. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

21 JFET - History of the JFET 1 The first practical JFETs were made many years later, in spite of their conception long before the junction transistor https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

23 Diode - Types of semiconductor diode 1 These are actually JFETs with the gate shorted to the source, and function like a two-terminal current-limiter analog to the Zener diode, which is limiting voltage. They allow a current through them to rise to a certain value, and then level off at a specific value. Also called CLDs, constant- current diodes, diode-connected transistors, or current-regulating diodes. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

27 Field-effect transistor - History, 1 The field-effect transistor was first patented by Julius Edgar Lilienfeld in 1926 and by Oskar Heil in 1934, but practical semiconducting devices (the JFET) were developed only much later after the transistor effect was observed and explained by the team of William Shockley at Bell Labs in 1947. The MOSFET, which largely superseded the JFET and had a more profound effect on electronic development, was invented by Dawon Kahng and Martin Atalla in 1960. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

28 Field-effect transistor - Types of field-effect transistors 1 The JFET (junction field-effect transistor) uses a reverse biased p–n junction to separate the gate from the body. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

29 Field-effect transistor - Types of field-effect transistors 1 The MESFET (metal–semiconductor field- effect transistor) substitutes the p–n junction of the JFET with a Schottky barrier; and is used in GaAs and other III- V semiconductor materials. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

30 Silicon carbide - Power electronic devices 1 In 2008, the first commercial JFETs rated at 1200 V were introduced to the market, followed in 2011 by the first commercial MOSFETs rated at 1200 V https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

31 MOSFET - Circuit symbols 1 Comparison of enhancement-mode and depletion-mode MOSFET symbols, along with JFET symbols (drawn with source and drain ordered such that higher voltages appear higher on the page than lower voltages):[http://www.circuitstoday.com/electr onic-circuit-symbols Electronic Circuit Symbols]IEEE 315[http://highered.mcgraw- hill.com/sites/dl/free/0073191639/366537/Ch apter_4.pdf#page=19 Microelectronic Circuit Design], Jaeger, Blalock - Figure https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

32 Schottky barrier - Devices 1 A MESFET, or metal–semiconductor field effect transistor|FET uses a reverse biased Schottky barrier to provide a depletion region that pinches off a conducting channel buried inside the semiconductor (similar to the JFET where instead a p–n junction provides the depletion region). A variant of this device is the high-electron-mobility transistor (HEMT), which also utilizes a heterojunction to provide a device with extremely high conductance. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

33 Triode - Operation 1 The triode is very similar in operation to the n-channel JFET; it is normally on, and progressively switched off as the grid/gate is pulled increasingly negative of the source/cathode. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

34 Threshold voltage 1 The threshold voltage of a JFET|junction field-effect transistor is often called 'pinch-off voltage' instead, which is somewhat confusing since pinch off for an MOSFET|insulated-gate field-effect transistor is used to refer to the channel length modulation|channel pinching that leads to current saturation behaviour under high source–drain bias, even though the current is never off. The term threshold voltage is unambiguous and refers to the same concept in any field-effect transistor. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

35 Vacuum tube - Description 1 The solid-state device which operates most like the pentode tube is the junction field-effect transistor (JFET), although vacuum tubes typically operate at over a hundred volts, unlike most semiconductors in most applications. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

38 Constant current diode 1 'Constant-current diode' (also called 'CLD', 'current-limiting diode', 'diode- connected transistor' or 'CRD', 'current- regulating diode') consists of a JFET with the gate shorted to the source, and it functions like a two-terminal current limiter or current source (analogous to a voltage- limiting Zener diode) https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

47 Overclocking - Cooling 1 Moreover, silicon-based junction gate field- effect transistors (JFET) will degrade below temperatures of roughly and eventually cease to function or freeze out at since the silicon ceases to be semiconducting so using extremely cold coolants may cause devices to fail. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

48 Hartley oscillator - Operation 1 The most simple of implementations shown here uses nothing but a Junction FET|JFET (in Common-drain configuration) and the LC tank circuit (here the single winding is tapped), plus a single battery; it will work, but probably with high distortion and high current drain (that could be improved by adding resistance between the source and the coil tap), and serves as an uncomplicated illustration of the Hartley oscillator operation: https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

49 Hartley oscillator - Operation 1 * the output from the JFET's source (emitter, if a Bipolar Junction Transistor|BJT had been used; cathode for a triode) has the same phase as the signal at its gate (or base) - and roughly the same voltage as its input (which is the voltage across the entire tank circuit), but the current is amplified, i.e. it is acting as a Buffer amplifier#Current buffer|current buffer or VCVS|voltage-controlled voltage- source. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

53 Low-noise amplifier 1 For low noise, the amplifier needs to have a high amplification in its first stage. Therefore Junction Field-Effect Transistor|JFETs and High Electron Mobility Transistor|HEMTs are often used. They are driven in a high-current regime, which is not energy-efficient, but reduces the relative amount of shot noise. Input and output Impedance matching|matching circuits for narrow-band circuits enhance the gain (see Gain- bandwidth product). https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

55 Transistors - Field-effect transistor (FET) 1 Metal–semiconductor FETs (MESFETs) are JFETs in which the Reverse- biased|reverse biased p–n junction is replaced by a metal–semiconductor junction.

60 AESA - Basic concept 1 The introduction of JFETs and MESFETs did the same to the transmitter side of the systems as well https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

61 Current source - Current-stable nonlinear implementation 1 A JFET can be made to act as a current source by tying its gate to its source. The current then flowing is the IDSS of the FET. These can be purchased with this connection already made and in this case the devices are called constant current diode|current regulator diodes or constant current diodes or current limiting diodes (CLD). https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

62 Current source - Constant current diode 1 The simplest constant-current source or sink is formed from one component: a JFET with its gate attached to its source. Once the drain-source voltage reaches a certain minimum value, the JFET enters saturation where current is approximately constant. This configuration is known as a constant-current diode, as it behaves much like a dual to the constant voltage diode (Zener diode) used in simple voltage sources. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

63 Current source - Constant current diode 1 Due to the large variability in saturation current of JFETs, it is common to also include a source resistor (shown in the image to the right) which allows the current to be tuned down to a desired value. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

64 MESFET 1 MESFETs are usually constructed in compound semiconductor technologies lacking high quality surface passivation such as gallium arsenide|GaAs, indium phosphide|InP, or Silicon carbide|SiC, and are faster but more expensive than silicon- based JFETs or MOSFETs https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

66 Nikon D2H 1 The 'Nikon D2H' is a professional-grade digital single-lens reflex camera introduced by Nikon Corporation on July 22, 2003. It uses Nikon's own JFET-LBCAST sensor with a 4.1 megapixel resolution, and is optimised for sports and action shooting that require a high frame rate. In 2005, the D2H was replaced by the D2Hs, which added new features derived from the 12 megapixel Nikon D2X|D2X digital SLR. The D2Hs was discontinued after the introduction of the Nikon D300|D300 and Nikon D3|D3 models. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

67 Flicker noise 1 Flicker noise is often characterized by the corner frequency fc between the region dominated by the low-frequency flicker noise and the higher frequency flat-band noise. MOSFETs have a higher fc (can be in the GHz range) than JFETs or bipolar transistors, which is usually below 2 kHz for the latter. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

69 Tube sound - Tube sound from transistor amplifiers 1 In 1982, Tom Scholz, a graduate of MIT and a member of Boston (band)|Boston, introduced the Rockman (music)|Rockman, which used JFET/BJT- based operational amplifiers and diode- based clipping circuits, but achieved a distorted sound adopted by many well known musicians. Advanced digital signal processing offers the possibility to simulate tube sound. Algorithms are currently available that transform digital sound from a CD or other digital source into a distorted digital sound signal. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html
