Original Abstract Submitted
An integrated circuit includes a first conductive path over a substrate, a coil structure over the substrate, and a ferromagnetic structure. The first conductive path is configured to carry a first time-varying current and to generate a first time-varying magnetic field based on the first time-varying current. The coil structure is magnetically coupled with the first conductive path, and is configured to generate an induced electrical potential responsive to the first time-varying magnetic field. The ferromagnetic structure includes an open portion. The first conductive path extends through the open portion of the ferromagnetic structure. The first conductive path includes a first conductive line below the ferromagnetic structure, a second conductive line above the ferromagnetic structure, and a first via plug coplanar with the ferromagnetic structure. The first via plug electrically coupling the first conductive line and the second conductive line.
