COUPLING OF ELECTROMAGNETIC-FIELDS TO COPLANAR STRIPLINES WITH DISCONTINUITIES

A circuit model for the coupling of externally generated electromagnetic fields to coplanar stripline interconnections with resistive and geometric discontinuities on lossy integrated circuit substrates is presented. The simplicity and fast speed of the model enable computer-aided analysis of externally induced electromagnetic noise in integrated circuit interconnects to be carried out. A general CAD algorithm is developed based on this model, and is applied to realistic coplanar strip interconnect line prototypes which are selected from a practical microwave integrated circuit. The effects of dielectric losses in the integrated circuit substrates and the discontinuities in the conducting tracks on the wave coupling are investigated in isolation.
