A new, simple and scalable inductor model for silicon-based spiral inductors has been presented in this paper. Compared to the conventional model, it can predict accurately the inductive characteristics and quality factor for inductors of different sizes. Introduction of a physical, non-frequency dependent resistive element to model conductor skin effects offers simplicity and accuracy to the modeling process of planar spiral inductors.
