Why closed loop differential amplifiers are difficult to null?
A. Due to compensating network
B. Due to feedback loop
C. Due to input offset voltage
D. None of the mentioned
Answer:A
Why closed loop differential amplifiers are difficult to null?
A. Due to compensating network B. Due to feedback loop C. Due to input offset voltage D. None of the mentioned
Explanation: The closed loop differential amplifiers are more difficult to null because the use of compensating network can change the common mode rejection mode.
