Abstract
A system to improve a multistage charge pump may include a capacitor, a first plate carried by the capacitor, and a second plate carried by the capacitor opposite the first plate. The system may also include a clock to control charging and discharging of the capacitor. The system may further include a power supply to provide a power supply voltage across the first plate and the second plate during charging of the capacitor. The system may also include a voltage line to lift the second plate to an intermediate voltage during discharging of the capacitor. The system may further include an output line connected to the first plate during discharging of the capacitor to provide an output voltage.
