Keywords: Early effect (NPN).svg Early effect or base-width modulation in an NPN BJT When the collector voltage is raised relative to the base and emitter i e the collector-base junction's reverse bias is increased the depletion region hashed area at the collector-base junction widens and the effective width W<sub>eff</sub> of the base is reduced This results in a higher collector i e output current own Inductiveload 2010-08-03 Early effect NPN zh hans svg Early effect NPN zh hant svg BJT circuits |
