Question

What does a common emitter amplifier do?

Answer 1

1. The common-emitter amplifier is a three-basic stage bipolar junction transistor.
2. The common-emitter amplifier is used as a current amplifier.
3. The output of a common-emitter amplifier is inverted, and it has a very high gain that can vary greatly from transistor to transistor.
4. The common emitter circuit layout offers medium input and output impedances, combined moderate current and voltage gains, and medium input impedance.
5. It is also used in radio frequency circuitry.
