Q. What are the different parameters of jfet ?

A bipolar junction transistor (BJT) is a current controlled device that is output characteristics of the device are controlled by the base current and not by the base voltage. However in a field effect transistor(FET), the output characteristics are controlled by input voltage(the electric field) and not by input current. This is the biggest difference between BJT and FET.There are two basic types of field effect transistor

a) JUNCTION FIELDEFFECT TRANSISTOR.

b) METAL OXIDE SEMICONDUCTOR TRANSISTOR.

A junction field effect transistor is a three terminal semiconductor device in which current conduction is by one type of carrier that is electrons or holes. To learn the different parameters of the JFET we first need to know the importance of certain terms.

PINCH OFF VOLTAGE: It is the minimum drain source voltage at which the drain current essentially becomes constantFor the proper functioning of the JFET it is necessary that drain voltage is greater than pinch voltage.
