WebMar 21, 2024 · In a BJT configuration when the emitter terminal is used as the output, the network is called an emitter-follower. In this configuration the output voltage is always a shade lower than the input base signal due to the inherent base to emitter drop. In simple terms, in this type of transistor circuit the emitter seems to be following the base ... Web5.8. Common-collector amplifier. Circuit description.

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 See more At low frequencies and using a simplified hybrid-pi model, the following small-signal characteristics can be derived.

WebApr 17, 2024 · Thus, for the positive swing, the voltage at the base will be: V B D C + V I N ≈ 7 V + 4 V ≈ 11 V at the peak of the input signal amplitude. And this means the transistor will enter the saturation region because of V B > V C + 0.5 V. And in saturation, the base-collector is in forward conduction. dr john cinats
