Abstract
An apparatus for driving a MOSFET, which includes a first gate driver adapted to generate a driving signal for a MOSFET, a switched capacitor circuit connected to the first gate driver and adapted to generate temporarily a negative voltage to counteract a spurious voltage occurred at the first gate driver; and a second gate driver comprising adapted to drive the switched capacitor circuit. The first gate driver and the second gate driver are powered by a same voltage source and controlled by a same control logic. The apparatus is adapted to momentarily generate a negative voltage that could counteract the spurious voltage generated by switching devices, and improve the switching performance.
