This paper introduces the experimental realization of the first integrated circuit of a multi-scroll continuous chaotic oscillator showing 3- and 5-scroll attractors. It is based on a variant of the Chua’s system. The most relevant issue is the implementation of a saw-tooth-like nonlinear function, which is designed by using floating gate MOS (FGMOS) transistors. Therefore, the realization of a voltage-to-current nonlinear cell by a piecewise-linear approach allows us to have only two external control inputs instead of numerous external voltage references, as usually done in current circuit realizations. Experimental results of the proposed integrated multi-scroll oscillator along with its corner analysis are provided.
