Claim of US Patent No. 9,935,048

1. An inductive device formed in a circuit structure comprising alternating conductive and insulating layers, the device comprising:in each of a plurality of the conductive layers, including at least a first layer and a second layer, traces forming:
a first trace forming a loop with an opening,
a second trace, within the loop of the first trace,
a third trace, outside the loop of the first trace, and
an interconnect segment;
a first pair of vias connecting the interconnect segment of the first layer to the second and third traces of the second layer, such that a conductive loop path with an opening is formed of the second trace on the second layer, the interconnect segment on the first layer, and the third trace on the second layer; and
a second pair of vias connecting the interconnect segment of the second layer to the second and third traces of the first layer, such that a conductive loop path with an opening is formed of the second trace on the first layer, the interconnect segment on the second layer, and the third trace on the first layer.
