For transistor action, which of the following statements are correct ?

A

Base,emitter and collector regions should have same size

B

Both emitter junction as well as the collector junction are forward biased

C

The base region must be very thin and lightly doped

D

Base,emitter and collector regions should have same doping concentrations.

Text Solution

Verified by Experts

The correct Answer is:
C
For transistors, Length of collector `gt` Emitter `gt` base
Doping of emitter `gt` Collector `gt` Base
Also emitter -base, junction is forward biased and base collector junction is reversed biased.
