Abstract

Charge pumps are circuits that produce the voltage higher than supply voltage or negative voltage. Today, charge pumps became an integral part of the electronic equipment. The integration of charge pumps directly into the system allows manufacturers to feed a complex system with many specific power requirements from a single source. However, charge pump efficiency is reduced by many phenomena. This paper is focused on the question of efficiency of proposed variant of the charge pump. In this article, the efficiency dependence on a number of stages, output current, clock frequency and MOSFETs sizes was simulated by Eldo. The aim of this study is to determine the MOSFETs sizes and theirs influence to efficiency and the output voltage. Complex optimization of the charge pump circuit will follow in further text.
