In electronics , a common-emitter amplifier is one of three basic single-stage bipolar-juntion (BJT) amplifier topologies, typically used as a voltage amplifier. In this circuit the base terminal of the transistor serves as the input, the collector is the output, and the emitter is common to both (for example, it may be tied to ground references or a power sulyy), hence its name. The analogous field effect transistor circuit is the common source amplifier.
