Discrete-time, cyclostationary phase-locked loop model for jitter analysis by Vamvakos, Socrates D., Stojanovic, Vladimir Marko, Nikolic, Borivoje

“…It is, therefore, important to develop the tools necessary to study and predict PLL jitter performance at design time. In this paper a discrete-time, linear, cyclostationary PLL model for jitter analysis is proposed, which accounts for the cyclostationary nature of noise injected into the loop at various PLL components. …”
