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 … 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. Under increased … See more In the forward active region the Early effect modifies the collector current ($${\displaystyle I_{\mathrm {C} }}$$) and the forward See more • Small-signal model See more The Early effect can be accounted for in small-signal circuit models (such as the hybrid-pi model) as a resistor defined as in parallel with the … See more
