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 the collector is … 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 … 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 buffer. In other words, the circuit has current gain … 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.

WebSep 16, 2024 · The common collector is also known as an emitter follower. The name comes from the fact that the emitter voltage “follows” the base voltage – the circuit has unit voltage gain. Working of Emitter Follower Figure below depicts an emitter follower circuit. WebA simple emitter follower is a great circuit element and will be found in most circuits. If care is not taken to run it at sufficient current, however, one can find it causes terrible distortion on transients due to capacitance on the emitter (Figure 21-3).This capacitance may be the collector-to-substrate capacitance of the current source supplying the emitter current. commercial cleaning services lawton

WebIn the Common Collector transistor configuration, we use the collector terminal as common for both input and output signals. This configuration is also known as emitter follower configuration because the emitter voltage … WebNov 19, 2024 · Common collector ("emitter follower") configuration as in the left diagram, have a lower output impedance due to the emitter feedback from the load. Also it has a voltage gain of almost unity, hence the "follower" part. That makes it a favourite for output stages, but it suffers from the junction drop issue mentioned above.
