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
A. active region
B. cutoff region
C. saturation region
D. cutoff and saturation
Correct Answer – 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.
