In the common mode, _______________?
Correct answer: C. an identical signal appears on both the inputs
- A. both inputs are grounded
- B. the outputs are connected together
- C. an identical signal appears on both the inputs
- D. the output signal are in-phase
Explanation
Common-mode operation means the same voltage signal is applied simultaneously to both inputs. An ideal differential amplifier rejects this identical component, producing zero differential output.
