Nonlinear Analysis of Charge Pump Phase-Locked Loops

چکیده
This paper presents an analysis of the nonlinear dynamics of a Charge Pump Phase-Locked Loop. The closed-loop circuit is modelled using decision-based equations developed by Van Paemel. State space plots; bifurcation diagrams and the presence of a chaotic attractor all indicate a significant level of underlying nonlinear phenomena. A calculation of the fractal dimension of the chaotic attractor is performed, and its basin of attraction is found through simulations. Finally, the results obtained are compared to the results of a previous analysis of a different CP-PLL model.
