Inductorless realization of chua’s circuit

Abstract

Nonlinear systems may produce many types of complex behaviour such as chaos. Simple electronic circuits may exhibit chaotic behavior. Among such electronic circuits, the Chua’s circuit is mostly used since it is quite simple and can easily be realized in the laboratory using standard electronic components. Experimentally Chaos can be observed using a simple circuit named Chua’s circuit and it is the first physical implemented system. Several alternative realizations are possible for Chua’s circuit. Inductors are used in most of the chaotic signal generators, which is inconvenient for various reasons. An Inductorlessrealisation of Chua’s circuit, which exhibits chaotic behaviour is presented in various circuits. This new realization consists of the Wien bridge circuit or op amp based circuit, which is in parallel with the nonlinear resistor. In this paper an Inductorless realization of Chua’s Circuit is presented using op-amps. Simulated results for two synthetic values of inductance L=18mH and L= 8.2mH is presented.
