First Claim
Patent Images
1. A skewed, co-spiral inductor structure, comprising:
- a first trace arranged in a first spiral pattern supported by a substrate; and
a second trace arranged in a second spiral pattern, the second trace having a same width as the first trace and coupled to the first trace, the first trace overlapping with the second trace in a plurality of orthogonal overlap areas, each orthogonal overlap area having a size defined by the width of the first trace and the width of the second trace, each orthogonal overlap area orthogonal to an adjacent portion of the first trace and an adjacent portion of the second trace, in which each straight, parallel edge of the first trace and the second trace partially overlaps by a predetermined amount in a reduced footprint of the co-spiral inductor structure.

Abstract
A skewed, co-spiral inductor structure may include a first trace arranged in a first spiral pattern that is supported by a substrate. The skewed, co-spiral inductor structure may also include a second trace arranged in a second spiral pattern, in which the second trace is coupled to the first trace. The first trace may overlap with the second trace in orthogonal overlap areas. In addition, each orthogonal overlap area may have a size defined by a width of the first trace and the width of the second trace. Also, parallel edges of the first trace and the second trace may be arranged to coincide.
