A Design Procedure for All-Digital Phase-Locked Loops Based on a Charge-Pump Phase-Locked-Loop Analogy [PDF]
In this brief, a systematic design procedure for a second-order all-digital phase-locked loop (PLL) is proposed. The design procedure is based on the analogy between a type-II second-order analog PLL and an all-digital PLL. The all-digital PLL design inherits the frequency response and stability characteristics of the analog prototype ...

Design and verification of data acquisition clock circuit based on dual-loop phase-locked loop
Background Digital measurement system based on ADCs (analog-to-digital converter) has higher requirement on the signal to noise ratio (SNR) of sampled data. Among all the factors, the jitter of sampling clock has the most prominent effect on SNR.

A Fast-Locking All-Digital PLL With Triple-Stage Phase-Shifting
This presents an all-digital phase-locked loop (ADPLL) system using triple-stage phase-shifting (TSPS) for fast locking. At the first stage, a phase-pulling multiplexer linearly pulls the phase of a feedback signal until the phase offset between the ...

Fractional spur suppression in all-digital phase-locked loops [PDF]
In this paper, fractional spur suppression techniques for all-digital PLLs (ADPLLs) are summarized. The attention is paid to the recently proposed digital-to-time converter (DTC)-based ADPLL architecture. DTC's nonlinearity dominates the fractional spurs contribution.
