Claim 0:
1. An inductive device comprising:
a first winding layer;
a second winding layer arranged over the first winding layer and connected to the first winding layer to form a plurality of turns around a first axis; and
a magnetic core arranged vertically between the first winding layer and the second winding layer, wherein the magnetic core comprises a portion extending along the first axis, the portion entirely over the first winding layer and entirely under the second winding layer;
wherein the portion of the magnetic core comprises a first magnetic segment, a second magnetic segment and a non-magnetic,
wherein the non-magnetic segment is arranged laterally between the first magnetic segment and the second magnetic segment along the first axis,
wherein the non-magnetic segment separates the first magnetic segment from contacting the second magnetic segment,
wherein the non-magnetic segment includes a first side and a second side opposite the first side, the first side slanted at a first angle relative to the first axis, the second side slanted at a second angle relative to the first axis, the first side contacts the first magnetic segment and the second side contacts the second magnetic segment, and the non-magnetic segment has a tapered shape.
