High Frequency Implementation of Sprott's Chaotic Oscillators Using Current-Feedback Op Amps

Abstract

High frequency implementation of Sprott's chaotic oscillators based on current-feedback op amps (CFOAs) is proposed. A Sprott's jerk function and four different types of nonlinear components are implemented using the attractively high-frequency features of the CFOAs operating in both voltage and current modes. Four trajectories of the chaotic attractors are demonstrated. The chaotic spectrums are easily scaled and extended to higher frequencies by a factor of 277 to 380.
