Application of field effect transistor (FET)

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