Abstract
An improved charge pump design useful in low power applications derives an alternative voltage from a supply voltage. The design can be constructed using PMOS manufactured according to standard processes such that triple well manufacturing processes are not required. The design can incorporate control gate circuitry to increase efficiency and decrease degradation due to the threshold voltage of the transistors used.
