Electrical characteristics of planar spiral inductors

摘要

This paper describes two types of PEEC-based methods for the analysis of planar spiral inductors. One approach is a high-level distributed network method (DNM), while the second is based on a relatively simple equivalent SPICE circuit. Theinductors are printed on lossless, grounded ceramic substrates and the metallization is assumed to have finite conductivity, but is infinitesimally thin, so that the formulation does not take in to account the skin effect. The methodology is applied toanalyze the electrical characteristics of several different inductors.
