Common Collector Amplifier Circuit Diagram. Common collector input impedance. Presenting the common collector amplifier.

Good transistor amplifiers essentially have the following parameters high gain high input impedance high bandwidth high slew. Common collector input impedance. The common collector transistor circuit configuration gains its name from the fact that the collector circuit is common to both input and output circuits the base being associated with only the input then the emitter with the output only.

Common base cb common collector cc and common emitter ce.

The common collector amplifier is also known as an emitter follower. Although the common collector amplifier is not very good at being a voltage amplifier because as we have seen its small signal voltage gain is approximately equal to one a v 1 it does however make a very good voltage buffer circuit due to its high input z in and low output z out impedances providing isolation between an input signal source from a.
