WebThe Early effect, is the variation in the effective width of the base in a bipolar junction transistor (BJT) due to a variation in the applied base-to-collector voltage.; A greater reverse bias across the collector-base junction increases the collector-base depletion width, thereby decreasing the width of the charge carrier portion of the base.; The collector depletion … WebWhat is BJT – Bipolar Junction Transistor? Bipolar junction transistor (BJT) is a bidirectional device that uses both electrons and holes as charge carriers. While Unipolar transistor i.e. field effect transistor uses only one type of charge carrier.BJT is a current controlled device. The current flows from emitter to collector or from collector to emitter …
