This review highlights various design and realization aspects of three commonly used charge pump topologies, namely, the linear, exponential, and the Fibonacci type of charge pumps. We shall outline the new methods developed recently for analyzing the steady and dynamic performances of these circuits. Some practical issues for the CMOS implementation of these charge pump structures will be critically discussed. Finally, some conventional voltage regulation methods for maintaining a stable output under a large range of loading current and supply voltage fluctuations will be proposed.
