Abstract :
In this paper the hardware implementation is discussed of a cellular nonlinear network (CNN) for analog simulation of reaction-diffusion partial differential equations. The elementary cell consists of the classic nonlinear circuit typical in these CNNs, except for the characteristic of the nonlinear resistor; that is chosen to be non-monotone. The control laws describing the contribution of the neighbor cells depend both on the currents and the voltages of the capacitors
