Scalable and broadband modeling of coupled on-chip spiral inductors up to 110 GHz

Abstract

Hub paper presents a scalable model capturing the magnetic coupling between adjacent on-chip spiral Inductors at frequencies from DC up to 110 GHz. The scalable model is comprised of ideal frequency-independent circuit elements. The element values are given by closed-form expressions In terms of the layout and process parameters. We have applied the modeling methodology to fabricated coupled on-chip inductors and verified the model accuracy through both full-wave EM simulation and measurement. The scalable model is fully compatible with common circuit simulators including Spice and ADS.
