ABSTRACT:
Described herein is a negative charge pump architecture that utilizes a triple-well, no body effect NMOS circuitry. The negative charge pump utilizes triple-well N channel high mobility transistor devices with the deep N wells grounded. The parasitic bipolar transistors may be avoided such that the charge transfer occurs mainly in the channel of the transistor device. With the increased mobility of the N channel devices, negative charge pumps using N channel transistors may be more efficient and may allow more current to flow than a comparable P channel charge pump.
