Luigi Fortuna, Ing. Mattia Frasca Catania, 29 Ottobre 2010

2 Outline con<nue New Time- delay system; Memristor- based Chua Circuits; con<nue Star networks of circuits;

3 Time- delay system Ikeda circuit con<nue

4 Time- delay circuit

5 Time- delay circuit Sallen Key filter H ( s) = 1 + C 1 2 ( R + R ) s + C C R R s Delay = 0.2 msec

6 Memristor- based Chua circuit New Resistor, Capacitor and Inductor Fundamental passive circuit elements Linear element: R, C, L are constant Nonlinear element: R is func<on of the independent variable

7 In the case of linear elements, M is a constant, memristance When M is itself a func<on of q, yielding a nonlinear circuit element, then the situa<on is more interes<ng.
