Zusammenfassung:Integrated circuits and coupled inductors with isotropic magnetic cores, and methods for fabricating integrated circuits and coupled inductors with isotropic magnetic cores are provided. In an embodiment, a coupled inductor includes a first inductor coil arranged around a coil center and a second inductor coil arranged around the coil center. The second inductor coil is interleaved with the first inductor coil, and the first and second inductor coils form an interleaved inductor coil. The coupled inductor further includes an isotropic magnetic core surrounding a portion of the interleaved inductor coil and passing through the coil center.
