Q1:

In a junction transistor, the collector cut-off current 'ICB0' reduces considerably by doping the

A emitter with high level of impurity

B emitter with low level of impurity

C collector with high level of impurity

D collector with low level of impurity

ANS:A - emitter with high level of impurity

How doping of an emitter affects ICB0?
