Chua circuits are the simplest circuit that meets the requirements to exhibit chaotic behavior and are cheap to construct with plenty of background research to check the accuracy of our results with. The initial design of the experiment was to synchronize multiple chaotic chua circuits acoustically to investigate ways of data masking for secure information transfer. This did not work out, and t...

In classical electronics, there are three passive circuit elements: the resistor, the capacitor and the inductor. In 1971, Leon Chua introduced a fourth “missing” element which he named a memristor — for memory resistor — by using symmetry arguments [Chua, 1971]. Chua also derived the properties of this element. However, it is only in 2008 that Strukov and co-workers [Strukov et al., 2008] foun...

We report experimental observation of cycle-cycle bursting near homoclinic bifurcation in a selfoscillating Chua oscillator when it is diffusively coupled to another excitable Chua oscillator. The excitable oscillator induces an asymmetry in the self-oscillating Chua oscillator via coupling. The coupling strength controls the strength of the asymmetry that plays a key role in transition to burs...

In this paper, an inductorless CMOS realization of Chua s circuit [IEEE Trans. Circ. Syst.––I 1985;32:798] is presented. The circuit is derived from the dimensionless form of Chua s circuit and can generate Rossler or double-scroll attractors by changing a single capacitor s value. Variables are represented in the current domain to facilitate adding or subtracting variables. New Gm–C representa...

A unidirectional coupling scheme is investigated in double scroll type chaotic oscillators that reveal interesting multiscroll dynamics. Instead of using self-oscillatory systems, in this scheme, double scroll chaos from one oscillator is forced into another similar oscillator in a resting state. This coupling scheme is explored in the Chua oscillator, a modified Chua oscillator and the Lorenz ...

Since its introduction to the research community in 1988, the Cellular Neural Network (CNN) (Chua & Yang, 1988) paradigm has become a fruitful soil for engineers and physicists, producing over 1,000 published scientific papers and books in less than 20 years (Chua & Roska, 2002), mostly related to Digital Image Processing (DIP). This Artificial Neural Network (ANN) offers a remarkable ability o...
