In 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 used as a voltage buffer. In this circuit the base terminal of the transistor serves as the input, the emitter is the output, and … See more The circuit can be explained by viewing the transistor as being under the control of negative feedback. From this viewpoint, a common-collector stage (Fig. 1) is an amplifier with full series negative feedback. In this configuration … See more The low output impedance allows a source with a large output impedance to drive a small load impedance; it functions as a voltage See more • Electronics portal • Common base • Common emitter • Common gate • Common drain • Common source See more At low frequencies and using a simplified hybrid-pi model, the following small-signal characteristics can be derived.

I prefer the common-emitter approach, because I find it more intuitive, but you might enjoy the common-collector amp if you prefer to avoid inversion—i.e., if you want higher illuminance to produce higher output voltage. WebAmplifier Impedances. Input impedance varies considerably with the circuit configuration shown in Figure below. It also varies with biasing. Not considered here, the input impedance is complex and varies with frequency. For the common-emitter and common-collector, it is base resistance times β. The base resistance can be both internal and ... opcs cell
