EC3361 - FREQUENCY RESPONSE CE AND CS AMPLIFIERS

The frequency response of both common emitter (CE) and common source (CS) amplifiers shows how their gain changes with signal frequency. At very low frequencies, the coupling and bypass capacitors cause the gain to drop because they block slow-changing signals. In the mid-frequency range, both amplifiers provide nearly constant gain, which is the useful operating region. At high frequencies, internal transistor (for CE) or MOSFET (for CS) capacitances reduce the gain due to their effect on the input and output. Overall, the CE amplifier (BJT-based) and CS amplifier (MOSFET-based) have similar frequency response shapes, with a flat mid-band and roll-offs at low and high ends, but the CE usually has higher gain while the CS offers higher input resistance.
