Abstract

This paper presents an integrated hybrid 6-stage voltage multiplier without using high-voltage-tolerant devices. The proposed architecture obtains a good area and efﬁciency performance by cascading the D ickson charge pumps and the symmetrical Cockcroft-Walton charge pumps, and paralleling them with the proposed auxiliary charge pumps formed by par- asitics. Implemented in a stan dard 0.18 µm CMOS process, the prototype provides a wide output range of 3–6 V and 30–240 µA load from a 1 V supply w
