How do you create a common emitter amplifier circuit?

Comprehensive AC coupled common emitter amplifier design

1. Choose transistor: As before, the transistor type should be chosen according to the anticipated performance requirements.
2. Calculate collector resistor: It is necessary to determine the current flow required to adequately drive the following stage.

What is common emitter amplifier circuit?

Common Emitter as an Amplifier is a configuration of the basic Bipolar Junction Transistor (BJT). As it consists of three basic terminals that are base, emitter and the collector but for the input and the output circuit connections it require minimum of four terminals.
