Original Abstract Submitted

A negative charge pump (NCP) with high reliability is shown. A first capacitor is coupled between the power terminal and the ground terminal while in the first state and disconnected from the power terminal and the ground terminal while in the second state. A second capacitor is coupled between the ground terminal and the output terminal of the NCP, wherein while in the second state, the second capacitor is further coupled in parallel with the first capacitor. The first capacitor is coupled to the power terminal and the ground terminal while in the first state through a first switch and the second switch, respectively. When switching from the second state to the first state, the first switch is closed before the second switch.
