Subtag of amplifier

Anything about common-collector (CC) amplifier circuits, also known as emitter followers.

A CC-amplifier is a BJT-based amplifier circuit where the output voltage is taken at the emitter, whereas the collector is connected to the power supply. Since the input voltage is applied at the base of the BJT, this makes the collector (which for the signal is grounded through the supply) the common reference for both input and output voltage signals, hence the name.
