The common-mode voltage gain is________________?
Correct answer: A. smaller than differentail voltage gain
- A. smaller than differentail voltage gain
- B. equal to differential voltage gain
- C. greater than differential voltage gain
- D. none of the above
Explanation
A differential amplifier is designed to amplify the difference between inputs while rejecting signals common to both, so its common-mode gain is much smaller than its differential gain.
