Global dynamics of arrays of nonlinear circuits

The analysis of the global dynamics of arrays of nonlinear circuits is a difficult task because they are described by a large set of nonlinear differential equations. Furthermore, it is essential for developing rigorous design algorithms, both in case of stationary behaviour (classical image processing applications) and in case of non-stationary behaviour (topographic wave computing).

We obtained some significant contributions on:

  • the study of the stability of the dynamic behavior (including chaos and bifurcations) and of the applications of cellular neural/nonlinear networks, with particular reference to image processing;
  • the study of the dynamics of nonlinear circuits and oscillators and of nonlinear dynamic arrays, through time-domain and frequency domain techniques (harmonic-balance) methods.
