Compact equivalent circuit model of two-layer spiral inductors
A compact lumped-element equivalent circuit model of two-layer integrated spiral inductors on silicon substrates is developed in this article. Based on this proposed model, excellent agreements are achieved between the measured and simulated S-parameters for different inductors. Also, both self- and mutual inductances of two-layer inductors are accurately extracted, and their overall performances are understood clearly. (C) 2003 Wiley Periodicals, Inc.
