Abstract
This paper presents a high performance ALL-PMOS charge pump suitable for implementation in standard CMOS processes. And only low voltage PMOS transistors are used. With the switching substrate technique and boosted transistor, the influence of body effect is eliminated and output voltage is greatly increased. A twelve-stage charge pump circuit is fabricated in a 0.35-mum double-poly CMOS technology. Measurements at 3MHz have shown that for power supply voltages of 2 V, 1.5V and 1V an output voltage of 15.5V, 10.4V and 3.6V can be generated respectively
