In this video, the derivation of the real output voltage of a differential amplifier is discussed. Starting with a simple circuit of a differential amplifier with MOSFETs, the formulas for the differential gain and the common mode gain are derived. With these formulas we finally define the equation for the real output voltage of our differential amplifier circuit.
