WebIn electronics, a common collector amplifier (also known as an emitter follower) is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically … WebFigure 13. Balanced slew rate follower waveforms. An alternate approach to improving the emitter follower is to reduce the effective r e through negative feedback. Reducing r e can be addressed by adding a second transistor to increase the negative feedback factor by increasing the open-loop gain. The single transistor is replaced by a pair with 100% …
