Inductor winding and method for preparing a layout of a Multi-Layer Spiral Inductor winding

A multi-layer spiral inductor winding comprising:

• a plurality of conductive layers, wherein each of the plurality of conductive layers include a plurality of conductive traces, and wherein each conductive trace comprises a conductive spiral of at least a fraction of one turn, and wherein at least one conductive trace of the plurality of conductive traces comprises a conductive spiral of two turns;
• an additional conductive layer, wherein the additional conductive layer includes a conductive trace, and wherein the conductive trace comprises a conductive bridge, and wherein the conductive bridge is configured to connect a second terminal electrode of the inductor winding to a conductive trace of the plurality of conductive layers;
• wherein a first terminal electrode of the inductor winding belongs to another conductive trace of the plurality of conductive layers;
• and wherein each of the conductive traces is isolated by an insulating material, and each conductive trace is electrically connected to a conductive trace of an adjacent conductive layer to form an inductor winding;
• and
• wherein an electrical current passes from a first terminal electrode connected to an outer conductive trace, into the conductive layer of the outer conductive trace, to a first adjacent layer of the conductive layer, to a second adjacent layer of the first adjacent layer, at last to a first terminal electrode to the inner conductive trace connected to the conductive bridge, and flows out of a second terminal electrode connected to the conductive bridge.
