voltage gain of CC

Understand the voltage gain of CC i.e. common collector (CC) configuration of unipolar transistors. Learn how this configuration provides high current gain and low output impedance, making it ideal for impedance matching in electronic circuits. Explore detailed analysis and practical examples to deepen your knowledge.

The small input voltage Vin is amplified by the transistor and we get output voltage Vo across emitter resistor of the transistor. In this configuration, when input signal is positive going, output is also positive and when input is negative output is also negative, as shown in above wave diagram.

In this circuit, the emitter is common to both input and output terminals of amplifier circuit. Thus, the input signal is connected between base & emitter and the amplified output signal is taken between collector & emitter, so that emitter is common.
