An Energy-Efficient Design Strategy for Dickson Charge Pumps with Linear Distributed Capacitance

This paper introduces a novel approach to designing energy-efficient Dickson charge pumps with linear distributed total capacitance. Theoretical analysis shows that the input energy can be minimized by opportunely choosing the optimal slope for the linear capacitance distribution and design guidelines are provided to get such value according to the given specifications. Simulation results using a 0.13-µ m CMOS technology confirm the validity of the proposed design strategy in various scenarios, allowing to achieve a percentage energy saving, in the worst case, of about 32%.
