Early-Effekt - Bipolartransistor - einfach erklärt - F.M.H.

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. Beim Bipolartransistor bewirkt der Early-Effekt, dass der Kollektorstrom von der Kollektor-Emitter-Spannung UCE abhängt, der Transistor also keine ideale Stromquelle ist. Die Kennlinie verläuft im typischen Arbeitsbereich linear, wie im rechts dargestellten Ausgangskennlinienfeld, und ihr extrapolierter Schnittpunkt mit der UCE-Achse wird als Early-Spannung UEA bezeichnet. Sie ist ein wichtiger Parameter zur Charakterisierung eines Bipolartransistors und zur Simulation, z.
