3:18 Types of FET
What is Field Effect Transistor (FET)?
The FET is a terminal device that uses an electric field to control the current flowing through the device.
The three terminals of the FET are known as Gate, Drain, and Source.
It is a voltage controlled device, where the input voltage controls the output current.
Application of FETs:
1) Amplifier
2) Oscillator
3) Analog Switch
4) Integrated Circuits
5) Buffer Amplifiers
Differences between the BJT and FET :
1) The FET is a unipolar device, while BJT is a bipolar device
2) The input impedance of FET is very high compared to BJT
3) The power consumption in FET is less than BJT
4) In size, the FETs are smaller than BJT
5) Thermally, FETs are more stable than BJT
Types of FET:
There are many types of FETs. But mainly there are two types of FET:
1) JFET (Junction Field Effect Transistor)
1.1 n-channel JFET
1.2 p-channel JFET
2) IG-FET (Insulated Gate Field Effect Transistor)
MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is the most common type of IG-FET, where a layer of SiO2 is used as an insulating layer to insulate the gate from the channel.
The MOSFET can be further classified into
2.1 Depletion-type MOSFET (n-channel and p-channel)
2.2 Enhancement-Type MOSFET (n-channel and p-channel)
This video will be helpful to all the students of science and engineering in understanding what is FET and the different types of FET.

[@abhiramanne9649]

Interesting fact. Notice the metal part of the FET shown at the beginning of the video. It is used for heat dissipation. It is screwed to a PCB board using the hole and then a small amount of heat gel (heat sink compound) is applied between the metal part and the PCB board.

Sir In FET amplifiers In which region should it be operated Saturation region or ohmic region

[@ALLABOUTELECTRONICS]

It is used in the saturation region. The thing is in FET the flat region is called saturation while in BJT it is called active region. But in both cases, where the I vs V curve is flat, that region is used for the amplification.

Nice explanation

[@vsproat5853]

Your comments of "FET is a unipolar device, while BJT is a bipolar device" and FETs being "Either free electron or Holes" and BJT being "both free electrons or holes" is unclear. Can you give some examples and clarification of the distinction you are making. Thank you in advance,

[@ALLABOUTELECTRONICS]

If you take the case of BJT (either NPN or PNP), here the charge carriers are both electrons and holes. (holes in P region and electrons in N region, as they are the majority carriers in the respective regions). So, we get current in BJT, it is due to both electrons and holes. That's why it is called a bipolar device. On the other end, in the FET, the current is due to the flow of charge carrier through the channel. The channel is either p-type or n-type. So, the current is either due to electrons or holes. That's why is called unipolar device. I hope it will clear your doubt.

[@maragathavallinarayanan4575]

In depletion mode holes I'll be major carrier and in forward mode electrons 'll be major carrier

Why silicon oxide is used for isolation?

[@ALLABOUTELECTRONICS]

The silicon dioxide acts as a insulating layer. And the thing is it is easy to deposit on silicon wafer during the fabrication.

Hello! Maybe someone can help me figuring out an issue I have: I'm simulating a gain stage for a guitar pedal using a J201 n-channel FET. The dataset reports the Idss (which should be the saturation current when Vgs=0) as

[@nareenshah7685]

Conduction due to elecrtons in one direction automatically mean the conduction of holes in the opposite direction.. Then how come the definition of a unipolar device comes into existence?

[@ALLABOUTELECTRONICS]

Unlike, BJT or diode, which involves both p-type and n-type region during the flow of current, Field effect transistors have dedicated channel for the conduction. (either n-type channel or p-type channel) So, the major contributing carrier in the flow of current is either electrons or holes. And hence it is called as unipolar device. I hope it will clear your doubt.
