Abstract
A charge pump circuit including a voltage converter and a pre-charging circuit is provided. The voltage converter is configured to receive a first voltage, and convert the first voltage into a second voltage. The first voltage is larger than the second voltage. The pre-charging circuit is coupled to the voltage converter. The pre-charging circuit is configured to charge a specified node of the voltage converter from a third voltage to a fourth voltage in a first charge period. The voltage converter charges the specified node from the fourth voltage to the first voltage in a second charge period. The fourth voltage is larger than the third voltage, and the third voltage and the fourth voltage are between the first voltage and the second voltage.
