We study the dynamical regimes that emerge from the strong coupling between two Chua's circuits with parameters mismatch. For the region around the perfect synchronous state we show how to combine parameter diversity and coupling in order to robustly and precisely target a desired regime. This target process allows us to obtain regimes that may lie outside parameter ranges accessible for any is...

The many roles of innexins, the molecules that form gap junctions in invertebrates, have been explored in numerous species. Here, we present a summary of innexin expression and function in two small, central pattern generating circuits found in crustaceans: the stomatogastric ganglion and the cardiac ganglion. The two ganglia express multiple innexin genes, exhibit varying combinations of symme...

We have investigated a chaotic circuit utilizing CMOS ring oscillators[1]. The circuit consists of two CMOS ring oscillators and two diodes. A CMOS ring oscillator is used for CMOS process performance test. This oscillator consists of a series of inverter circuits. It has a very simple structure. Therefore, we consider that the proposed circuit is realized very easily. In the past studies, we h...

Coupled oscillators are complicated high-dimensional dynamical systems. They can exhibit a wide variety of rich dynamics which could lead to novel applications in engineering. In this brief we describe a torus-doubling phenomenon observed from four mutually coupled Chua’s circuits. The qualitative dynamical behavior of the coupled system is robust, yet the exact behavior is very sensitive to th...

This paper presents synchronization of coupled chaotic circuits as an array topology when coupling strength has different value depending on distance between the chaotic circuits. By using computer simulations, we observe interesting synchronization phenomena. Namely, several types of synchronization are observed by depending on arrangement method of chaotic circuits.

In this paper identical and generalized synchronization and the complex dynamics of hyperchaotic circuits are exploited for designing reliable cryptosystems. Since chaotic additive masking, chaotic switching and chaotic parameter modulation methods can have a low degree of security, an attempt to overcome this drawback is made by utilizing hyperchaotic circuits which make available several chao...

We consider a single Chua’s circuit and a system of a unidirectionally coupled n-Chua’s circuits driven by a biharmonic signal with two widely different frequencies ω and Ω, where Ω ω. We show experimental evidence for vibrational resonance in the single Chua’s circuit and undamped signal propagation of a low-frequency signal in the system of n-coupled Chua’s circuits where only the first circu...
