Abstract: A magnetic structure can include: a first magnetic component and a second magnetic component; two magnetic columns configured to form a magnetic flux loop with at least part of the first magnetic component and at least part of the second magnetic component, where at least one of the two magnetic columns is wound with one or more windings; and where the at least part of the first magnetic component is located between the two magnetic columns.

Abstract: An integrated substrate can include: a top structure having a plurality of first pads for mounting electronic devices, where each of the first pads is electrically coupled with a corresponding electronic device, such that each of the first pads has a corresponding potential; a bottom structure having a plurality of second pads for coupling with peripheral circuits; a plurality of intermediate metal layers stacked up/down and located between the top structure and the bottom structure; a first type of penetrating connection structures configured to couple the intermediate metal layers and a part of the first pads, such that the intermediate metal layers have the same potential as the part of the first pads; and a second type of penetrating connection structures configured to couple the intermediate metal layers and the second pads, such that the second pads have the same potential as the part of the first pads.
