In this paper, we propose a fast-lock-in all-digital phase-locked loop (ADPLL), which is designed with the cell library and described by Hardware Description Language (HDL). The proposed ADPLL uses a novel 2-level flash time-to-digital converter (TDC) to lock in within 2 reference clock cycles. The novel digitally controlled oscillator (DCO) achieves high-resolution with 0.93ps resolution and can extend the controllable range easily. In addition to high-resolution, the power consumption of the proposed DCO can be lowered as 110uW(@200MHz). The proposed ADPLL can be easily ported to different process as a soft intellectual property (IP), making it very suitable for System-On-Chip (SoC) applications as well as system-level power management.
