Abstract
A bootstrap circuit includes an input terminal, an inverting input terminal, an output terminal, an inverting output terminal, a first sub-bootstrap circuit, a second sub-bootstrap circuit, and a charging path providing circuit. The first sub-bootstrap circuit includes a first bootstrap capacitor, a first charging path, a first discharging path, and a first high voltage providing path. The charging path providing circuit includes a third charging path. In response to a high voltage level inputted into the input terminal, the first charging path and the third charging path are turned on, the first bootstrap capacitor is charged to a capacitor voltage, and the first discharging path is turned on to discharge the output terminal. In response to a low voltage level inputted into the input terminal, a first superimposed voltage including the high voltage level and the capacitor voltage is provided to the output terminal.
