A new charge pump is proposed which provides improved jitter characteristics for a phase-locked loop (PLL). The PLL with the proposed charge pump is implemented with 0.6 µm CMOS technology. The measured RMS output jitter is as much as 28% smaller than that of a PLL with a previously reported charge pump structure.
