Document Type and Number:
WIPO Patent Application WO2004027996
Kind Code:
A3
Abstract:
An n-channel MOS transistor negative-voltage charge pump is disclosed in which the bulks of the n-channel MOS transistors (26, 28) are biased in such a manner as to prevent turning on the parasitic bipolar transistor inherent in the CMOS environment of the charge pump structure.
