WebQuestion: The early effect in a BJT is caused by. Options. A : fast turn on. B : fast turn off. C : large collector base reverse bias. D : large emitter base forward bias 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 … See more In Figure 1, the neutral (i.e. active) base is green, and the depleted base regions are hashed light green. The neutral emitter and collector regions are dark blue and the depleted regions hashed light blue.
