Abstract :
In this paper the domain decomposition method (DDM) for conformal modules is used to get simple analytic expressions for the inductance of planar spiral inductors. DDM is found to be valid for inductors of arbitrary spiral shape, as long as the conductor width is uniform along the spire. Expressions of a rectangular spiral inductor and a circular spiral inductor are obtained by DDM, and the computed results are compared with previously published expressions.
