Exact Analysis and Physical Realization of the 6-Lobe Chua Corsage Memristor

A novel generic memristor, dubbed the 6-lobe Chua corsage memristor , is proposed with its nonlinear dynamical analysis and physical realization. The proposed corsage memristor contains four asymptotically stable equilibrium points on its complex and diversified dynamic routes which reveals a 4-state nonlinear memory device . The higher degree of versatility of its dynamic routes reveal that the proposed memristor has a variety of dynamic paths in response to different initial conditions and exhibits a highly nonlinear contiguous DC V - I curve. The DC V - I curve of the proposed memristor is endowed with an explicit analytical parametric representation . Moreover, the derived three formulas , exponential trajectories of state , time period , and minimum pulse amplitude , are required to analyze the movement of the state trajectories on the piecewise linear (PWL) dynamic route map (DRM) of the corsage memristor. These formulas are universal, that is, applicable to any PWL DRM curves for any DC or pulse input and with any number of segments . Nonlinear dynamics and circuit and system theoretic approach are employed to explain the asymptotic quad-stable behavior of the proposed corsage memristor and to design a novel real memristor emulator using off-the-shelf circuit components.
