A Methodology for Design and Modeling of Optimum Quality Spiral Inductors

This paper presents a methodology, based on the regularization theory, to find, in the whole geometric parameter space, the planar spiral inductors with optimum quality factor. A new technique, based on Debye fitting approximation, has been applied to extract a passive equivalent circuit model of these inductors. This model provides an accurate wideband frequency characterization up to 16 GHz.
