A common-collector (CC) amplifier is also known as an emitter follower (or a voltage follower) due to the fact that the output voltage "follows" the input by being approximately equal to the input voltage. The amplifier is shown in Figure (a), in which the collector forms a common terminal between the input and output circuits, and resistors R1, R2, and RE are determined by biasing. Capacitors CB and CE are chosen large enough to appear as short circuits at the lowest frequency of interest in the input signal vS. The output voltage vL is taken across the load resistor RL. The small-signal ac equivalent circuit of the amplifier is shown in Figure (b), whose analysis yields the following results:
