Behavioral Modeling of Delay-Locked Loops and its Application to Jitter Optimization in Ultra Wide-Band Impulse Radio Systems
This paper analyzes the sources of jitter in a DLL and presents a behavioral model for fast DLL optimization. An algorithm to simulate the DLL in open loop is demonstrated. This procedure, together with the behavioral modeling, greatly reduces the simulation time of DLL when compared to the closeloop DLL simulation. In order to optimize the DLL performance, the dependence of the output jitter versus the power consumption is studied.
