BJT Amplifiers: Common Emitters and DC Analysis

WebHence they are called unipolar. But in BJT, both electrons and holes take part in conduction. Hence they are called bipolar. Input circuit (gate -source) is reverse biased. Hence input impedance is high. The input circuit of BJT is forward biased. Hence BJT has low input impedance. FET is a voltage driven device. BJT is a current operated device. WebFeb 24, 2012 · A Bipolar Junction Transistor (also known as a BJT or BJT Transistor) is a three-terminal semiconductor device consisting 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. WebThere are two types of current gain in BJT i.e. α and β. Where IE is the emitter current IC is the collector current IB is the base current Common Base Configuration: Common Base Voltage Gain In common base configuration, BJT is used as voltage gain amplifier, where the gain AV is the ratio of output voltage to input voltage: Where α = IC / IE canon hf 700
