Performance of non-linear amplifier based phase locked loop systems in presence of channel perturbations

摘要

The tracking performance of non-linear amplifier based conventional second order phase locked loop (PLL) and charge Pump phase locked loop have been examined numerically by solving the system equations in the presence of lognormal type of fading signal. Some analytical results for non-linear amplifier based conventional phase locked loop and charge pump phase locked loop are also incorporated to confirm the simulation results and for the choice of optimum design system parameter.
