Applications of FET (field effect transistor)

Applications:

There are some important applications of field effect transistor (FET) which are given below.

The FET is a voltage controlled device due to this it is used in operational amplifier as voltage variable resistor.
It is commonly used as input amplifiers in devices i.e. voltmeters, oscilloscope, and other measuring devices, due to their high input Impedance.
Field effect transistor (FETs) are used in mixer circuits to control low inter modulation distortions.
It is used in large scale integration (LSI) and computer memories because of its small size.
FETs are used in low frequency amplifiers due to its small coupling capacitors.
It is also used in radio frequency amplifiers for FM devices.
It is used for mixer operation of FM and TV receiver.
