In an amplifier the emitter junction is
WebA bipolar junction transistor is a three-terminal semiconductor device that consists of two p-n junctions which are able to amplify or magnify a signal. It is a current controlled device. The three terminals of the BJT are the base, the collector, and the emitter. WebA transistor acts as an Amplifier, where the signal strength has to be increased. ... As one junction is between the emitter and base, that is called as Emitter-Base junction and likewise, the other is Collector-Base junction. Biasing is controlling the operation of the circuit by providing power supply. The function of both the PN junctions is ...
