摘要： Provided is a boosting circuit having a small circuit scale. When a node (Vg) is reset by a reset transistor (M3) after a boosting operation has been finished, the reset transistor (M3) is controlled based on a power supply voltage to reset the node (Vg). Therefore, another boosted voltage is not required for the reset, and hence an additional boosting circuit required for the another boosted voltage is unnecessary as well. As a result, the circuit scale of the boosting circuit is reduced correspondingly to the additional boosting circuit.
