Semiconductor Devices: The Emitter Follower
Channel: Electronics with Professor Fiore
Date: 2020-04-19

Here, we present an explanation of the emitter follower, or common collector transistor amplifier. Known generically as voltage followers, the ideal follower has a non-inverting voltage gain of 1, high input impedance and low output impedance. A follower is ideal for coupling a high impedance source to a low impedance load.
