Abstract :
The mass matrix resulting from a finite-element-method (FEM) based electromagnetic analysis possesses favorable properties that can be exploited to reduce the computational time and memory cost for large-scale circuit modeling. In this paper, a mass-matrix based frequency-domain FEM method is developed for the analysis of integrated circuits. Its convergence is theoretically proved, and its efficiency is accelerated by a reduced eigenspace method.
