Multiscroll oscillator based on floating gate CMOS inverter

The design of a multiscroll chaotic oscillator based on the realization of a sawtooth function by using floating gate MOSFETs (FGMOS), is introduced. Basically, we propose the implementation of a FGMOS inverter to generate the nonlinear functions which are responsible of the equilibrium points of a continuous chaotic dynamical system, allowing the generation of multiple scroll attractors. Spice simulations show the behavior of the nonlinear cell, along with the generation of multiscroll chaotic attractors.
