1. An integrated circuit comprising:
- a plurality of quadrangular coils, each of the plurality of quadrangular coils including a first wiring and a second wiring that are alternately connected to each other,wherein the first wiring is formed on a first layer and the second wiring is formed on a second layer situated over the first layer, such that the first wiring perpendicularly intersects the second wiring in a plan view,wherein the coils are partly overlapped with each other in a diagonal direction that connects opposite corners of the coils, andwherein the coils include a first coil and a second coil partly overlapped with each other in the diagonal direction, and a corner of the first coil and a corner of the second coil are entangled with each other such that the first wiring and the second wiring extending from the corner of the first coil are situated under the second wiring and over the first wiring, respectively, extending from the corner of the second coil.

Abstract
An integrated circuit includes multiple quadrangular coils including a first wiring and a second wiring that are alternately connected to each other and formed on different layers in a manner perpendicularly intersecting each other. The coils are partly overlapped with each other in a diagonal direction that connects opposite corners of the coils. The coils preferably have the same structures. A target coil among the coils preferably partly overlaps with another coil among the coils in two diagonal directions that connect opposite corners of the target coil.
