www.aosmd.comThe MOSFET capacitances are non-linear as well as a function of the dc bias voltage. Figure 7a shows how capacitances vary with increased VDS voltage. All the MOSFET capacitances come from a series combination of a bias independent oxide capacitance and a bias dependent depletion (Silicon) capacitance. The decrease in capacitances
