FET (Field Effect Transistor)
Introduction:
FET is a three terminal device. In which current is controlled by an electric field (voltage)
A FET operates on the principal that the thickness and hence the resistance of a conducting change of semiconductor material may be requlated (controlled)by the amount at pontentical applied to get Input termainl (that is the number at current carrier) in conducting region is controlled of an electric field at the surface at the semi-conductor.
There are 2 types of FET
1)Junction Field Effect Transistor (JFET)
2)Metal Oxide Semi-conductor Field Effect Transistor (MOSFET)
OR
Insulated Gate Field Effect Transistor
Both of these can be either "P" Channel Or "N" Channel Device.
