1. A stacked differential amplifier circuit to receive a differential input signal and generate a differential output signal, the stacked differential amplifier circuit comprising:
a differential amplifier circuit configured to receive the differential input signal, the differential amplifier circuit comprising a plurality of unit cell amplifier circuits arranged in parallel, each of the unit cell amplifier circuits configured to be selectively activated or deactivated by a corresponding tail current switch circuit; and
a stacked amplifier circuit configured to generate the differential output signal based on an output from the differential amplifier circuit.
