Bypassed common emitter amplifier
WebCalculate the approximate voltage gain (AV) for the following bypassed common-emitter amplifier circuit, assuming a quiescent (DC) emitter current value of 750 µA. Also calculate the quiescent DC voltage measured at the transistor’s collector terminal with respect to ground (VC). Assume a silicon transistor: Vout Vin Rbias +20 V 750 µA ... WebMar 28, 2024 · The gain of the grounded common-emitter amplifier is G = − R C / r e = − R C I C / 25 m V. Here, r e is the intrinsic emitter resistance, ie the reciprocal of the transconducance. If the input signal is large enough, it will substantially modulate the collector current I C, and hence the gain.
