Abstract
Abstract
A circuit of fast-setting charge pump on-chip is designed based on the Dickson circuit. The charge pump circuit, which is improved, increases the initial node voltage. With the consideration of the current mismatch, the accurate clock of the duty circle below 50% is proposed. The HSPICE simulation result indicates that the setting time from 0V to 20V only needs 51.650μs for the charge pump, and it is faster than the traditional Dickson charge pump 26.03μs. In summary, the settling time of the output voltage of the charge pump is prominently decreased and the performance of the charge pump is obviously improved.
