Abstract

A charge pump is a kind of DC to DC converter that uses capacitors as energy storage elements to create a higher or lower voltage power source. Charge pumps make use of switching devices for controlling the connection of voltage to the capacitor. Charge pumps have been used in the nonvolatile memories, such as EEPROM and Flash memories, for the programming of the floating-gate devices. They can also be used in the low-supply-voltage switched-capacitor systems that require high voltage to drive the analog switched. This paper includes voltage analysis of different charge pumps. On the basis of voltage analysis a new charge pump is proposed.
