A comprehensive phase-transfer model for delay-locked loops

This paper presents a comprehensive model for analyzing the behavior of an analog delay-locked loop (DLL). Unlike previous models, the proposed version includes both constant and variable phase-offset terms, making it possible to calculate jitter transfer characteristics, stability, and static phase errors from a single unified model. The topology more closely approximates the underlying architecture of the DLL, resulting in improved accuracy and enabling better tradeoffs between bandwidth, stability, and power.
