本文介绍了第一个具有三涡卷和五涡卷吸引子的多涡卷连续混沌振荡器的集成电路的实验实现。它是基于一个变种的蔡氏系统。最相关的问题是锯齿状非线性函数的实现，这是通过使用浮栅MOS（FGMOS）晶体管设计的。因此，通过分段线性方法实现电压-电流非线性单元允许我们仅具有两个外部控制输入，而不是如电流电路实现中通常所做的那样具有多个外部电压基准。实验结果的建议集成多涡卷振荡器沿着其角落分析。
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.
