Question

The V-I characteristic of a FET is shown below. For small signal amplification the device should be biased in the region

• A. BC
• B. OA
• C. AB
• D. AC

Hint:

FETs operate in the saturation region (AB) for linear amplification.

Answer 1

The Correct Option is C

For small signal amplification, a FET must operate in the active region (also called the saturation region), where the drain current is relatively constant. From the V-I graph, this region corresponds to AB.
