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

A

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

B

Base, emitter and collector regions should have same size.

C

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

D

The base region must be very thin and lightly doped.

Step-by-Step Solution

For Bi-polar junction transistor, the length profile is LC>LE>LBL_C > L_E > L_B and doping profile is E>C>BE > C > B. For transistor action, the Base-emitter junction is forward biased and the Base-collector junction is reversed biased.
