A two-port VCCS chaotic oscillator and quad screw attractor

This paper reports an approach to the synthesis of chaotic oscillators consisting of capacitors and two-port voltage-controlled current sources (2PVCCSs). As a paradigm, we present a chaotic oscillator consisting of one linear 2PVCCS, one hysteresis 2PVCCS and two capacitors. The oscillator exhibits a quad screw attractor and the chaotic behavior can be guaranteed theoretically. Using, a test circuit, the quad screw attractor can be verified in the laboratory.
