WebIn this video, the early effect in the BJT (base width modulation) is explained. By watching this video, you will learn the following topics:0:00 Introductio... The Early effect, named after its discoverer James M. Early, 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, for example, increases the collector–base depletion width, thereby decreasing the width of the charge carrier portion of the base.
