Common mode voltage gain of an op-amp is generally
A. >1
B. =1
C. <1
D. None of the mentioned
Answer:C
Common mode voltage gain of an op-amp is generally
A. >1 B. =1 C. <1 D. None of the mentioned
Explanation: The amplitude of common mode output voltage is very small and often insignificant compared to common-mode input voltage. Therefore, the common mode voltage gain is generally much smaller than 1.[/expand]
