To understand the DC and AC operation of a differential amplifier. To measure DC voltages and currents in differential amplifier.

To obtain measured values of differential-mode gain 𝐴𝑣𝑑𝑚, common-mode gain 𝐴𝑣𝑐𝑚 and common-mode rejection ratio 𝐶𝑀𝑅𝑅.

Explore the operation of differential FET amplifier with resistive and active loads: Measure the common and differential mode open circuit voltage gains; Measure the frequency response of gains and common mode rejection ratio.
