WebAug 16, 2024 · A Bipolar Junction Transistor (BJT or BJT Transistor) is a three-terminal semiconductor device composed of two P-N junctions that can amplify or magnify a signal. The three terminals of the BJT are the base, the collector, and the emitter. The primary function of a BJT is to amplify current, which allows BJTs to be used as amplifiers. WebThis type of transistor biasing configuration, often called self-emitter biasing, uses both emitter and base-collector feedback to stabilize the collector current even further.
