06031445 is referenced by 121 patents and cites 7 patents.

A invention provides a transformer for use in integrated circuits, comprising four layers of conductive lines, separated from each other by first, second and third insulating layers. First conductive vias traverse the second insulating layer to connect said second and third pluralities of conducting lines, to form a first winding. Second conductive vias traverse the first, second and third insulating layers to connect said first and fourth pluralities of conducting lines to form a second winding, about and approximately concentric with said first winding.
