FIELD EFFECT TRANSISTORS ● The FET is a three terminal semiconductor device in which the current flow through the conduction region is controlled by an electric field. ● FET is also known as Voltage controlled device, since the flow of current in the output side is controlled by Input voltage ● The operation of the FET depends on the majority carrier alone. So it is called Unipolar device. ● Thermally more stable. ● It is immune to radiation. ● No offset voltage occurs. ● Due to its high input impedance, it is preferred for amplifiers. ● Less space is required and less noisy. FET is classified into two types. (i) Junction field effect transistor (JFET) (ii) Metal oxide semiconductor Field effect semiconductor(MOSFET)Advantages of FET:-
