Title: Planar miniature inductors and transformers

Abstract: The planarization of inductive components by reducing standard coileddesigns to single turn, open ended designs from which the requiredparameters are obtained by scaling the length. Single turn designs havingmagnetic material encircling the conductors along their full length enablethe thinnest form. The single turn, open ended form also enables theinductive component to be routed according to any shape in the plane or onany conformal surface. The single turn inductors do not need to coil hencethere is no overlap necessary in the plane. The planar form allowsintegration of inductive components with integrated circuits. Theseinductive components can be embedded in other materials. They can also befabricated directly onto parts.
