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.
