Abstract
According to one embodiment, a resonant gate driver comprises a resonant path configured to couple a gate of a power transistor to a supply capacitor, and a low impedance path configured to couple the gate of the power transistor to a voltage rail. The resonant gate driver selectively utilizes the resonant path during charging and discharging of the gate, and selectively utilizes the low impedance path to couple the gate to the voltage rail when the gate is neither charging nor discharging. A method for use by the resonant gate driver for driving the power transistor comprises charging and discharging the gate of the power transistor by selectively coupling the gate to a supply capacitor through a resonant path, and utilizing a low impedance path to selectively couple the gate to a voltage rail when the gate is neither charging nor discharging.
