Zusammenfassung:	A charge pump includes a first unidirectional conducting device, a flying capacitor, a second unidirectional conducting device, an output capacitor, a first switch, and a second switch. The first unidirectional conducting device unidirectionally couples a supply voltage to an internal node. The flying capacitor is coupled between the internal node and a clock signal. The second unidirectional conducting device unidirectionally couples the internal node to an output node. The output capacitor is coupled between the output node and a ground. The first switch couples a discharge node to the ground according to a discharge signal. The second switch couples the output node to the discharge node according to the voltage of the internal node.
