Conical inductor modeling using equivalent circuit technique

Abstract

This paper describes innovative high accuracy models that have been developed for broadband conical inductors, in particular to predict Piconics' SMT conical series (0.22 to 8 uH). Several models are available from Modelithics which include substrate-scalable versions that have been validated against series-connected inductors on a range of substrates and fixed-substrate models for shunt configurations that accurately depict device behavior over a wide frequency range. Measurement validations for the generated models include DC resistance and S-parameters above 40 GHz on multiple substrates.
