Conical inductor modeling using equivalent circuit technique

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.
