Abstract :
The various nonideal phenomena in the charge pump circuits are discussed in this paper. The relevant effects and solutions are also presented. Based on the above analysis, we propose a new simple charge pump circuit, which is suitable for high speed PLL circuits and can work at a low supply. The charge pump is designed in a standard CMOS 0.18 mum technology. The SPECTRE simulation results show the capability of high-frequency operation (1GHz) with very low-power consumption (28muW) at the 1V power supply. Moreover, the output waveform does not exhibit spurious jumps
