Abstract:
A gate driving circuit includes a bootstrapping circuit, a pre-charge circuit, and an output control circuit. The bootstrapping circuit is composed of a bootstrapping capacitor and a transistor. A first terminal of the bootstrapping capacitor has a first voltage during a first duration. The pre-charge circuit is connected to the first terminal of the bootstrapping capacitor. The pre-charge circuit boosts the first terminal of the bootstrapping capacitor from the first voltage to a second voltage during a second duration. The bootstrapping circuit boosts the first terminal of the bootstrapping capacitor from the second voltage to a third voltage during a third duration. The output control circuit is connected to the first terminal of the bootstrapping capacitor. The output control circuit boosts the first terminal of the bootstrapping capacitor from the third voltage to a fourth voltage during a fourth duration.
