Chaotic phenomena in a switched capacitor phase-locked loop

Discusses the chaotic phenomena in a switched-capacitor phase-locked loop proposed by D. Asta and D. Green (1990). They prove the existence of the logistic chaos by a one-dimensional map. It is clarified that, in the map, there exist parameter values where attractors coexist. Moreover, two-parameter space in which the chaotic phenomena occur is calculated. The analytical estimate is verified by circuit experiments.<>
