Fet switching speed figure of merit

WebThe simple answer is that a certain amount of energy (E) is dissipated each time a transistor switches. Each time you switch, you dissipate that same amount of energy. If you siwtch at some rate (F) Hz, then you will dissipate that energy F times per second. Therefore the dissipated wattage (W) due to switching losses is ....
