Question 39
ECNAT2 marksNeeds review
In the figure shown, the
transistor acts as a switch. 
For the input
as shown in the figure, the transistor switches between the cut-off and saturation regions of operation, when T is large. Assume collector-to-emitter voltage at saturation
and base-to-emitter voltage
. The minimum value of the common-base current gain (
) of the transistor for the switching should be ________.Log in to check the answer
