Fet switching speed figure of merit
WebJul 18, 2024 · A Figure of Merit (FoM) is often used by designers to choose these desirable characteristics such as this T=RC constant. It is also used to design faster turn off and slower turn on to prevent commutation "shoot thru" when both N and P channel devices are ON at the same time, using a parallel diode and R values to drive the gate faster OFF. WebHTGMOS exhibits a significantly improved performance as compared with the conventional silicon trench-gate MOSFET (CTGMOS) in terms of ON-state resistance, transconductance, breakdown voltage, switching time, and figure of merit (FOM).
