Summary :

This work proposed a high-performance charge-pump circuit for phase-locked-loop (PLL) applications. The proposed charge-pump circuit is composed of a pair of wide-swing current mirror and symmetric pump circuits which can provide wide output range and have no jump phenomenon. The proposed charge-pump circuit has been designed and simulated by using the TSMC 0.35 µm 1P4M CMOS technology. Simulation results show the feasibility of proposed structure for low-voltage high-frequency applications.
