MOSFET as a Switch - Using Power MOSFET Switching

WebAs the power MOSFET’s performance improved, it followed the evo-lution of CMOS technology introduced in the late ‘70s to produce integrated circuits. Typically, power … 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. design process book example
