An improved implementation of Chua's circuit using dual output current conveyor is presented. The present proposal offers the advantages of low component count, current mode processing, availability of current across inductor and availability of voltage across inductor in form of current. The application of present circuit in designing low hardware inductorless hyperchaotic circuit is also presented. The paper concludes with a discussion of advantages of present proposal of Chua's circuit and inductorless hyper chaotic circuit thus designed over their earlier counterparts. The designs are adequately supported by SPICE simulation results.

SUMMARYA 3D modular cellular nonlinear network (CNN) architecture-based test bed, with four-neighbor connectivity, used to study synchronization phenomena in oscillatory and chaotic networks is designed. The architecture is implemented as hardware panels including a standalone robust Chua's circuit kit. The details of electronic implementation along with several test cases of connecting Chua's circuits in different topologies are provided. Test cases are adequately supported by oscilloscope traces.

A plug-and-play kit that can be used as a teaching aid in high school has been designed, which mimics the behavior of recently discovered TiO 2 based memristor. The circuit uses easily available off-the-shelf components to emulate a memristor. SPICE simulations and lab results are shown to validate the proposed circuit.
