Application of field effect transistor (FET)

There are some application of field effect transistor (FET) are given below,

• 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.
