WebFrom the small-signal model, we see that the amplifier consists of a current source and two resistors. Since the two resistors appear in parallel, we can merge them as R_o^\prime = … WebTo calculate the small signal voltage gain of the common emitter or source amplifier we need to insert a small signal model of the transistor into the circuit. The small signal models of the BJT and MOS FET are actually very similar so the gain calculation for either version is much the same.
