Abstract :
Switching characteristics of a power MOSFET formed on a silicon-on-insulator (SOI) substrate are analyzed by device simulation including the external circuit. The SOI power MOSFET is shown to have shorter turn-on and turn-off times than the corresponding MOSFET. Experiments are carried out on a prototype SOI power MOSFET, and good agreement is obtained between the simulation and the experiment. The SOI power MOSFET is shown to be a promising switching device for DC/DC converters operating at several megahertz
