Abstract :
This paper presents the design of a 1.0 V 150-550 MHz 65 nm ADDLL using a novel coarse-fine architecture and differential circuit techniques. When running at 550 MHz, this nanometer ADDLL achieves a peak-to-peak jitter of only 5 ps with the shortest 4 locking cycles, while consumes only 0.67 muW/MHz, about 72% reduction compared to the existing most power efficient ADDLL.
