Question

Is the voltage gain of common emitter amplifier constant, irrespective of magnitude of the input signal?

Open in App

Solution

The voltage gain of a CE amplifier varies with signal frequency. It is because reactances of the capacitors in the circuit changes with signal frequency and hence affects the output voltage. The curve drawn between voltage gain and the signal frequency of an amplifier is known as frequency response. Below figure shows the frequency response of a typical CE amplifier.
