A differential amplifier with two transistors. The output equals the voltage difference between the two inputs. This is the common-mode case, where both inputs are the same. The change in the common-mode signal at the output is much smaller than in the differential mode. But, as shown here, it still swings more than desired. This can be improved by using a current source.
