Question

Explain about JFET Characteristics.

Answer 1

Characteristics of JFET: The characteristics of JFET is defined by a plotting a curve between the drain current and drain-source voltage. The variation of drain current with respect to the voltage applied at drain-source terminals keeping the gate-source voltage constant is termed as its characteristics. Basically, the characteristics are of two types that are output characteristics or drain characteristics, and the another is transfer characteristics.

Answer 2

Characteristics of Junction Field Effect Transistors (JFET)

Fast switching.

For low frequency operation, source and drain can be interchanged.

Gate voltage that controls drain current.

Single majority carrier.

Small in size.

High “Z” input.
