Abstract:
A single-stage gate driving circuit with multiple outputs includes a first bootstrapping circuit, a first pre-charge circuit, a first output control circuit, a second bootstrapping circuit, a second pre-charge circuit, and a second output control circuit. During a first duration, the first pre-charge circuit precharges a first node to a first voltage. During a second duration, the first bootstrapping circuit boosts the first node from the first voltage to a second voltage, and the second pre-charge circuit precharges a second node to a fourth voltage. During a third duration, the first output control circuit boosts the first node from the second voltage to a third voltage, and the second bootstrapping circuit boosts the second node from the fourth voltage to a fifth voltage. During a fourth duration, the second output control circuit boosts the second node from the fifth voltage to a sixth voltage.
