The transfer characteristics of a base b...

The transfer characteristics of a base biased transistor has the operation regions, namely, cutoff, active region and saturation region. For using the transistor as an amplifier it has to operate in the

A

active region

B

cutoff region

C

saturation region

D

cutoff and saturation

Text Solution

Verified by Experts

The correct Answer is:
A
When the transistor is used in the cutoff or saturation region it acts as a switch. On the other hand for using the transistor as an amplifier, it has to operate in the active region.
