<i>n</i> -scroll chaos generator using nonlinear transconductor

Abstract

A novel chaotic oscillator capable of generating n-scroll chaos by relying on a multiple-cycle nonlinear transconductor is reported. The function of this nonlinearity can be mathematically represented via smooth hyperbolic tangent functions and its implementation only requires properly-biased bipolar differential-pair cells. The structure of the proposed oscillator is much simpler than existing n-scroll chaos generators.
