D. All of the mentioned
Answer:A
To increase the input resistance, the differential amplifier replaces transistor by
A. Current mirror B. Current repeater C. Darlington pair D. All of the mentioned
Explanation: Higher value of input resistance can be obtained by using Darlington pair in place of transistor. 2. In Darlington pair differential amplifier the current gain is given as 100. Where IB1=5µA and IC1=0.35mA. Determine IC2
