ROBUST GENERALIZED PEEC METHODOLOGY FOR FULL-WAVE ANALYSIS OF INTEGRATED CIRCUITS

A numerically stable extension of the Partial Element Equivalent Circuit interpretation of the electric field integral equation for the modeling of arbitrarily shaped interconnections and integrated passives in high-speed/high-frequency integrated circuits is presented in this paper. The proposed methodology utilizes triangular cells for the discretization of conductor surfaces and triangular prisms for the modeling of finite dielectrics. Its numerical stability at very low frequencies is achieved through an appropriate transformation of the resulting system matrix, and makes possible the broadband electromagnetic analysis from very low (almost dc) to multi-GHz frequencies
