WebAug 1, 2011 · Table 2. Charge characteristics due to parasitic MOSFET capacitance. The ability to fully turn on at a lower gate voltage results in lower losses in the gate driver and has an impact on turn-on times for the transistor. For instance, gate source capacitance (Q GS) normalized to a MOSFET sized to provide 1 ?
