Charge pump circuits operating at voltage levels above that of the power supply usually suffer from gate-oxide voltage overstress. Such reliability problem has become a concern especially as the gate-oxide thickness is scaled down. Devising charge pu

Reliability problems such as gate-oxide voltage overstress have become a concern for CMOS circuits as the gate-oxide thickness is scaled down. Gate-oxide overstress is particularly worse for charge pump circuits because they usually operate in high v
