Question

Explain the differences of CB, CE and CC configurations.

Answer 1

This page compares CB vs CE vs CC transistor configurations and mention difference between CB, CE, CC transistor modes. These modes are used in various transistor based applications as per characteristics mentioned below.

As we know transistor is solid state equivalent of a triode valve. It is a solid state, current gain device which has 3 terminals. The terminals are collector, base and emitter. It is made by both the p-type and n-type materials. Hence it is available in PNP and NPN configurations. It is referred as bipolar transistor.

There are three basic configurations of transistors viz. Common Base (CB), Common Emitter (CE) and Common Collector (CC) used in electronic circuits. Following are the important characteristics of these different modes or configurations. Based on these they are used for different applications. Figure-1 depicts all the three transistor configurations used in various applications of electronic circuit.
