Differential Amplifiers - Differential and Common Mode Gain, Derivation, Formulas, Simplifications

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, we derive the formulas for the differential mode gain as well as the common mode gain. With these formulas we finally define the equation for the real output voltage of our differential amplifier circuit.
