WebAs its name suggests, in common emitter, the emitter is common between input and output. The input is applied between base & emitter while output is taken between collector & emitter. It can be simply recognized by looking at the circuit. If the emitter is grounded while input and output are taken from the base and collector respectively. WebSep 21, 2014 · With no bypass capacitor across the emitter resistor, negative feedback is used to stabilize the DC operating voltages (Q-point) of the transistor amplifier. Hence the AC gain is reduced. By applying a capacitor across the emitter resistor, you restore some of the AC gain (frequency dependent) without affecting the DC balance point (Q-point).
