Summary:An automated design and optimization tool for all digital phase locked-loop (ADPLL) system is presented in this paper. The ADPLL system design goal is to determine the digital loop filter (DLF) coefficients using analytic noise models and phase noise simulation results for each ADPLL block, then the DLF coefficients are optimized using evolutionary optimization method to achieve the optimum locking time and phase noise of the ADPLL. The system simulation results of the ADPLL designed by the tool show good agreement with the system's required specifications.
