Description
Summary:This paper discusses a quadrature phasing technique that betters the performance of charge pumps. Quadrature phasing is a simple implementation of the multiphasing approach, which improves both the static performance, with a lower output resistance, and the dynamic performance, with a faster rise time. Models of the output resistance and rise time were developed for the Dickson-Pelliconi and heap charge pumps with arbitrary number of stages. Then simulation results demonstrated the benefits of quadrature phasing, which lead to increased efficiency of all the circuits that are powered by, and incorporate charge pumps as the means of power supply, without requiring additional space or more demanding clocking requirements.
