Question

For a CE mode amplifier, υi is 20 mV and υo is one volt. Calculate voltage gain.

Answer 1

The gain will be 100.

Explanation:

When we apply a signal at the input terminal of CE transistor, working as an amplifier, it amplifies the signal. To get the amplified output, input is multiplied with the gain. Now, we are going to calculate that gain for 10mV input and 1V output.

We know that:

Gain = output / input

Gain = 1/10m

Gain = 100
