Abstract
An inductive device is formed in a circuit structure that includes alternating conductive and insulating layers. The device includes, in a plurality of the conductive layers, traces forming a respective pair of interleaved loops and at least one interconnect segment in each of the plurality of the conductive layers. In each layer among the plurality of the conductive layers, at least one loop in the respective pair is closed by jumpers to an interconnect segment formed in another layer above or below the layer.

An inductive device formed in a circuit structure comprising alternating conductive and insulating layers, the device comprising, in a plurality of the conductive layers, traces forming a respective pair of interleaved loops and at least one interconnect segment in each of the plurality of the conductive layers, wherein in each layer among the plurality of the conductive layers, at least one loop in the respective pair is closed by jumpers to an interconnect segment formed in another layer above or below the layer.
A method for producing an inductive device in a circuit structure that includes alternating conductive and insulating layers, the method comprising:
- forming, in each of a plurality of the conductive layers, traces that define a respective pair of interleaved loops and at least one interconnect segment;
- and
- forming jumpers between the conductive layers, such that in each layer among the plurality of the conductive layers, at least one loop in the respective pair is closed by the jumpers to an interconnect segment formed in another layer above or below the layer.
