WebEarly effect. The Early effect is the variation in the width of the base in a BJT due to a variation in the applied base-to-collector voltage, named after its discoverer James M. Early. A greater reverse bias across the collector–base junction, for example, increases the collector–base depletion width, decreasing the width of the charge neutral portion of the … WebEarly voltage, often denoted by the symbol VA. Large-signal model. In the forward active region the Early effect modifies the collector current (IC) and the forward common-emittercurrent gain (βF), as typically described by the following equations:[1][2] Where.
