Pull-in behavior of second order phase locked loop(PLL) with a sinusoidal comparator has been investigated in the absence of noise. The approach is based on the fact that the unlocked behavior of first order PLL can be applied to the transient analysis of second order PLL. With this method, closed form expressions for the pull-in behavior and pull-in time of second order PLL have been obtained.
