WebOct 12, 2013 · BJT (bipolar junction transistor) are widely used an amplifier, oscillator, switch etc. It is a current-driven device ( MOSFET is voltage driven), the output current is equal to the input current times a factor which is called Gain. A basic BJT has three pins: the Base, Collector, and Emitter.
WebFeb 1, 2024 · The current flow through the BJT (Ic) is controlled by the size of the base current (Ib). Every BJT has a particular ratio between the size of this 'collector' current and the 'base' current which is called current gain (beta). Unless you really want to know the physics of the BJT forget about terms such as majority carriers, minority carriers ... the queen abdicatingWebbipolar transistor.
