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.

How FETs Work - The Learning Circuit

In this episode, Karen talks about the two common types of field-effect transistors, MOSFETs and JFETs. Find out the differences between them, and what it means for them to work in depletion and enhancement modes. Connect with Karen on the element14 community: http://bit.ly/2FLa664
My skills : Love you
s : Seems that the D-mosfet was not forward biased to increase the channel width in the last portion of the video, wouldn't the gate need a positive charge,drawing negative charges into the channel from the substrate, increasing the width of the channel and there by increasing current through the mosfet, the battery, it seems, should of been switched in polarity from the last screenshot but wasn't? Great videos though and much appreciated, thanks :)
Muhammad khalidkhan : Respectable Teacher your motivation very nice
Anne van Gulik : Hi Karen, I love your videos! Im just a bit lost in the word "bias", I don't understand what it is and in the video you say things like "the more bias the gate becomes" and "to increase the bias". I understand the principle of reversed bias or forward bias, I just don't follow it when it is used in a different context. Can you please enlighten me :) thanks so much!
Yosor Shishakli : love you zelda shirt

The FET (field effect transistor)

This is the first of four movies (see below) The Field Effect Transistor made its entrance into industry in the shape of the JFET. Some time later, its younger cousin, the MOSFET, made a splash that continues to make it the centerpiece of digital electronic systems this day. I find it "natural" to explain the evolution from the JFET to the MOSFET using the simpler JFET mechanisms first. That is the approach: we begin with the JFET and then we move on to the MOSFET (in three aditional movies). I have also included a few tutorials, all listed below. I hope you find them useful.

1. The FET


2. The MOSFET 1/3


3. The MOSFET 2/3


3. The MOSFET 3/3


4. Tutorial on MOSFET part 1


5. Tutorial on MOSFET part 2


6. Tutorial on MOSFET part 3


7. Tutorial on MOSFET part 4


8. Final Exam's MOSFET question part 1


9. Final Exam's MOSFET question part 2

Krisi Qyra : you said that the gate current is 0 the same goes for every type of mosfet?
ADeLoR kchok : thank you sir god bless you
ThePreppar : Thank you, very thorough. Much appreciated.
Shayhan : lmao! Not BobaFET
DANI M : Thank you ... 2020
