Analysis of Integrated Circuit Systems by an Innovative Wavelet Based Scattering Matrix Approach

Abstract—This paper proposes the use of scattering parameters ( -parameters) in the wavelet domain for the analysis of coupled multiconductor transmission lines, high-speed integrated circuits, and interconnects.  -parameters-based computing techniques are widely used in the analysis of networks characterized by a large number of integrated devices and interconnects. The theoretical and practical definition of the wavelet-based  matrix is shown, and then some numerical examples of its use and potential in the analysis of systems with linear and nonlinear terminations is shown and compared with other numerical techniques. The computational costs and the memory requirements of the wavelet representation of scattering matrix are also addressed.
