Abstract :
This paper proposes a new charge pump structure for phase locked loop (PLL) applications. The circuit is optimized to minimize the amount of glitches in the output current. It is designed in a standard CMOS 0.18μm technology, and it operates from a 1V power supply. The output voltage has a relatively wide range, from 100mV up to 900mV, and does not exhibit any spurious jump phenomenon. Simulation results in HSPICE show the capability of high-frequency operation (500MHz), with very low-power consumption (60μW).
