Abstract
A circuit for generating positive and negative boosted voltages, comprising first and second voltage booster circuits, respectively for positive and negative voltages, which have output terminals interconnected at a common node. It comprises two tristate logic gate circuits for coupling said voltage booster circuits to a positive supply voltage generator and additional tristate logic gate circuits for driving the phases of charge pump circuits incorporated into the booster circuits. This voltage generating circuit may be integrated in single-well CMOS technology.
