Fast analysis of RFIC using multilevel Green´s function interpolation method

A full-wave multilevel Green´s function interpolation method (MLGFIM) loop-tree (LP) algorithm based on PMCHWT integral equations is proposed for the fast analysis of EM system in RFIC. To overcome the low-frequency breakdown problem, the LP basis function is adopted to preserve both inductive and capacitive phenomena at very low frequency. PMCHWT integral equations can solve composite metallic and dielectric structures of RFIC with the surface discretization. With the fast algorithm MLGFIM, the computation time and memory are greatly reduced. A spiral inductor example demonstrates its accuracy and efficiency.
