Abstract
An integral equation method used for capacitance extraction for axially symmetric geometries is extended in this paper to calculate the via-plane capacitances in shared-antipad via structures, by changing the circular ring cells to arc ones. The proposed method is validated with a commercial finite element method based tool for a typical structure used in modern high-speed printed circuit design.
