What is meant by differential input signals in a MOS differential amplifier?

Differential amplifiers apply gain not to one input signal but to the difference between two input signals. This means that a differential amplifier naturally eliminates noise or interference that is present in both input signals.

How do differential amplifiers work?

A differential amplifier multiplies the voltage difference between two inputs (Vin+ - Vin-) by some constant factor Ad, the differential gain. A differential amplifier also tends to reject the part of the input signals that are common to both inputs (V_in+ + V_in)/2 . This is referred to as the common-mode signal.
