Abstract
A charge pump circuit includes a capacitor, a first switch between the capacitor and a power supply terminal, a second switch between the capacitor and an output terminal, a third switch between the output terminal and the capacitor, a fourth switch between the capacitor and a ground terminal, and a control unit configured to generate control signals for the switches. The control signals include first signals generated during a first period that cause first and third switches to be in an ON state and second and fourth switches to be in an OFF state, second signals generated during a second period that cause first and third switches to be in an OFF state and second and fourth switches to be in an ON state, and third signals generated between the first and second periods, that cause the ON/OFF state of each of the switches to be switched at different times.
