Abstract
An accurate equivalent network for modeling the skin effect is presented. Rules for choosing the number of parallel R-L branches for precisely modeling the skin effect in spiral inductors are presented. The concept has been verified using high-Q on-chip inductors realized using wafer level packaging techniques. A good agreement between measurements and simulations has been obtained up to the first resonance.
