Abstract :
In this work we propose a technique for bootstrapping CMOS switches in voltage doublers and double charge pumps. The technique prevents short-circuit losses, improves driving capability, and enables efficient operation at low supply voltages. The effectiveness of our approach is verified through simulations of design examples, which also illustrate the improvements in conversion efficiency, voltage gain, and output resistance.
