Memristor-based and time-delay nonlinear circuits

Abstract

The pioneering works of Prof. Leon O. Chua constructing electrical circuit (named Chua s circuit) which can display chaotic behaviors open a period with fruitful researches about nonlinear circuits. A considerable amount of different nonlinear circuits has been introduced and their numerous applications have developed instantaneously. Complex dynamical characteristics of nonlinear circuits are used to model complex systems, to generate random numbers or to secure informations. There are three nonlinear systems which have received much attention recently: time delay system, Cellular Neural Network and memristive system. In this thesis we investigate how the properties of these nonlinear systems can be efficiently exploited to build novel chaotic systems and to observe novel complex phenomena.
