Three-phase oscillator modified for chaos

A three-phase sinusoidal oscillator employing negative-type second-generati on current conveyors (CCII) is modified for chaos using a recently introduc ed grounded diode-inductor composite. The resulting chaotic oscillator is d escribed by a fifth-order system of differential equations with switching-t ype nonlinearity. A possible implementation based on current feedback op am ps (CFOAs) is investigated. PSpice circuit simulations agree well with nume rical simulations of the derived mathematical model.
