Abstract :
This paper describes a design of digital phase-locked loop (DPLL), which has low-power consumption and low jitter features. A novel voltage controlled oscillator (VCO) and Phase-Frequency Detector (PFD) are proposed to reduce the total power consumption and phase error of the DPLL. The proposed VCO has low power consumption, and the PFD is a “three-state” structure with a dead zone of 5 ps. The power consumption of the proposed DPLL is lower than 6.7 mW, and the output-frequency range of the oscillator is from 200 MHz to 650 MHz. The worst-case cycle jitter is lower than 160 ps, and long-term jitter is lower than 220 ps. We confirm the results based on 0.5 μm CMOS technology and 3 V supply voltage
