Quizplus · Accepted Answer

In a common mode differential amplifier, both outputs (Vout1 and Vout2) have the same amplitude and are in phase with each other, but they are out of phase with their respective inputs. This is because the common mode signal is equally present at both inputs, leading to outputs that mirror each other in amplitude and phase but are inverted relative to the input signals.
