发明名称 Voltage generator
摘要 According to one embodiment, a voltage generator includes a step-up circuit and a limiter circuit. The step-up circuit outputs a first voltage to a first node. The limiter circuit includes first and second resistive elements, first and second capacitive elements, a switch element, and a comparator. The first resistive element is between the first node and a second node. The second resistive element is connected to the second node. The first capacitive element is between the first and second nodes. The switch element connects the second capacitive element to the second node at the same time that the first node is connected to a load. The comparator compares the potential at the second node with a reference potential.
