In the CB configuration, the input current is the emitter current I E and the output current is the collector current I C. The collector voltage V CB is kept constant throughout this. When the emitter voltage is applied, as it is forward biased, the electrons from the negative terminal repel the emitter electrons and current flows through the emitter and base to the collector to contribute collector current. ![]() The common base connection for both NPN and PNP transistors is as shown in the following figure.įor the sake of understanding, let us consider NPN transistor in CB configuration. The name itself implies that the Base terminal is taken as common terminal for both input and output of the transistor. In every configuration, the emitter junction is forward biased and the collector junction is reverse biased. The three types of configurations are Common Base, Common Emitter and Common Collector configurations. Using these 3 terminals the transistor can be connected in a circuit with one terminal common to both input and output in three different possible configurations.
