<P> 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 . </P>
