Patent ID: 7973636

Claim:
An apparatus comprising: a first winding side of a transformer having a plurality of winding components, in which the winding components of the first winding side are disposed on a first set of alternating supporting substrate layers, wherein each supporting substrate layer of the first set of supporting substrate layers supports at least two winding components of the plurality of winding components and wherein the plurality of winding components of the first winding side are electrically coupled together; and a second winding side of the transformer having a plurality of winding components, in which the winding components of the second winding side are disposed on a second set of substrate supporting layer or layers that are interleaved between the first set of supporting substrate layers, wherein the winding components of the second winding side are disposed as a composite substantially encircling geometric shape, such that from a perpendicular perspective with respect to the first and second set of supporting substrate layers, the winding components of the first winding side and winding components of the second winding are respectively overlayed.
