What is Common Emitter Amplifier Overview about?

1) A common emitter amplifier amplifies the input voltage, with the output voltage having the opposite polarity of the input. The DC voltage gain is given by -RC/RE. 2) A common collector amplifier (emitter follower) has a voltage gain of 1 but provides current gain. It is used to match high impedances to low impedances to maximize power transfer. 3) Transistor amplifiers can be modeled using hybrid-pi or hybrid-T equivalent circuits to calculate input and output impedances for circuit analysis and design
