What is EARLY effect? Ans: In CB configuration when reverse bias voltage V CB increases, the width of depletion region also increases , which reduces the … WebIn CB configuration a variation of the base-collector voltage results in a variation of the quasi- neutral width in the base. The gradient of the minority-carrier density in the base therefore changes, yielding an increased collector current as the collector-base current is increased. This effect is referred to as the Early effect.

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 common-emitter current gain ($${\displaystyle \beta _{\mathrm {F} }}$$), as typically described by the following equations: 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 See more • Small-signal model See more florence sc turntableWebEarly effect or base width modulation: The early effect is the variation in the width of the base in a bipolar transistor due to a variation in the applied base-to-collector voltage.
