BJT DefinitionA 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. A BJT is a type of transistor that uses both electrons and holes as charge carriers.A signal of small amplitude if applied to the base is available in the amplified form at the collecto

Bipolar Junction Transistor DefinitionA Bipolar Junction Transistor (BJT) is a three-terminal device. It can function as either an amplifier or a switch, requiring one input circuit and one output circuit. To handle this with only three terminals, one terminal serves as a common connection for both input and output. The choice of the common terminal depends on the application. There are three types of transistor connections: common base, common emitter, and common collector. Common Base Transist
