Abstract
Official abstract text for this publication.
An integrated circuit transformer structure includes at least two conductor groups stacked in parallel in different layers. A first spiral track is formed in the at least two conductor groups, the first spiral track includes first turns of a first radius within each of the at least two conductor groups, and second turns of a second radius within each of the at least two conductor groups, the first and second turns being electrically connected. A second spiral track is formed in the at least two conductor groups, the second spiral track including a plurality of adjacent turns of one or more radii within each of the at least two conductor groups and disposed in a same plane between the first and second turns in each of the at least two conductor groups.
