Transient Analysis of Second-Order Charge Pump PLL for Phase Step Input

: This paper presents the analysis and simulation of second-order charge pump phase-locked loop by applying the phase step at the entrance and calculates the fast lock and transient time and the effects of loop parameters such as capacitor, resistor, loo filter current, control voltage oscillator at the at the fast lock investigated and plotted in the diagram at transition time. All simulation was performed by matlab software.
