Abstract :
A systematic procedure of simulating charge pump based delay locked loops (DLLs) represents in this paper. The presented procedure is based on the systematic modeling of the DLL components in Matlab Simulink simulator. The system has been designed for 1Hz input clock signal that by changing the whole system scale, it can be used for every other input frequencies. The simulation results in Matlab and design considerations for DLL based frequency multiplier are presented.
