Early spannung transistor

WebA transistor is a semiconductor device with at least three terminals for connection to an electric circuit.In the common case, the third terminal controls the flow of current between the other two terminals. This can be used for amplification, as in the case of a radio receiver, or for rapid switching, as in the case of digital circuits.The transistor replaced the … WebThe Early voltage is a parameter describing the variation of the transistor collector or drain current in the active or the saturation region of operation with the VCE or VDS , …

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. B. …
