We will continue this series by looking at the final configuration for a transistor amplifier, the common collector amplifier or emitter follower, before examining the equivalent circuits using ...

Solid-state device technologies, which are available to the amplifier designer ... current of the transistor is of the right order to place the collector potential near its desired operating voltage.

Up to the present, stabilization has either been by minimizing these effects by suitable circuit design ... the inherent high efficiency of the transistor amplifier, and limited range of stability.
