Abstract :
An all-digital phase-locked loop (ADPLL) for high-speed clock generation is presented in this paper. The proposed ADPLL architecture can be implemented with standard cells. And the ADPLL implemented in a 0.35 μm 1P4M CMOS process can operate from 40 MHz to 540 MHz. The p-p jitter of the output clock is less than ±170 ps, and the rms jitter of the output clock is less than 39 ps. A systematic way to design the ADPLL with specified standard cell library is also introduced. The proposed ADPLL can easily be ported to different processes in a short time. Thus it can reduce the design time and design complexity of ADPLL, making it very suitable for System-On-Chip (SoC) applications
