Crosstalk bounds in interconnects with random parameters

Abstract

In this paper a method to determine upper and lower bounds for crosstalk signals in interconnects is presented. Assuming a quasi TEM propagation interconnects are modeled as transmission lines whose equivalent circuit is considered. From the frequency response of the equivalent circuit the dependence of the far end voltages on lines parameter is derived and the interval of variation is determined. Considering uncertain geometric characteristic of a simplified but meaningful geometry results have been obtained showing that the derived bounds accurately confine the actual space of variation of the crosstalk signals.
