In an ideal differential amplifier, common-mode gain should be?

  • AZero
  • BUnity
  • CInfinite
  • DEqual to differential gain
Report an error
Correct Answer: A. Zero
Explanation: An ideal differential amplifier responds only to the difference between its inputs and rejects signals common to both, so ideal common-mode gain is zero.
Reference: Standard analog electronics: differential amplifier
