Abstract
An extraction tool developed with advanced algorithm to compute MEMS (Micro Electro Mechanical System) inductance is presented. The algorithm is based on solution of Laplace equation by Finite Element Method followed by current density computation. The energy of resulting magnetic field is estimated by Monte Carlo sampling. The extractor developed estimates precisely the inductance offered by MEMS inductor. The impact of micro surface roughness on the estimation of components is a concern because of surface to volume ratio increasing with scaling. The tool demonstrates the impact of micro surface roughness on the estimation of inductance.
