Is common collector same as emitter follower
WebA common design strategy is to design for a “generous base current,” which could be satisfied with an effective gain of roughly 10. C. The Emitter-Follower Amplifier The most important circuit in this chapter is the emitter follower (see figure 6.4 below). WebThe Emitter or Source follower is often called a common Collector or Drain amplifier because the collector or drain is common to both the input and the output. This amplifier configuration, figure 9.4, has its output taken from the emitter/source resistor and is useful as an impedance matching device since its input impedance is much higher ...

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.
WebIt’s called that because the emitter “follows” the base voltage, less the b-e voltage drop. Because of this drop, voltage gain is actually slightly less than 1, but the current gain is … WebJul 12, 2024 · Emitter follower/Common collector confusion. I'm in the need of a buffering circuit for a project and I would like to use a common collector amplifier or emitter …
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. WebWhen photocouplers are used as switching devices, the phototransistor on the output side operates simply as a switch. When a regular transistor is used as a switch, the operation differs depending on whether the load is connected to the emitter (emitter follower or common collector) or the collector (common emitter).
