  • Patent number: 11863081
    Abstract: A single/Multi-phase PMIC built on silicon substrate with coil layers processed on top of the PMIC layers' is provided. The integrated coil is in a spiral form, with a gap at the center of the coil, making additional metal routing not required. The integrated coil has connection pads located in the center gap of the spiral form, limiting the overall inductor resistance to the device only. The on-die inductor may have a magnetic core wrapping the windings. The spiral form may be implemented in a circular design, or a racetrack (elongated spiral) design. The coil layers may be implemented as multiple coil layers or as a single coil layer, connected in parallel (with the same I/O pads), reducing the resistance and maintaining the inductance.

  • Patent number: 11756726
    Abstract: New and Useful magnetic structures are provided. One feature of the magnetic structures is that they are configured to help minimize the air gap reluctance, improving the magnetic structure's coupling coefficient. Another feature is that reducing the windings AC impedance of a magnetic structure is produced by shielding the winding under ears formed of magnetic material. Still another feature is that leakage inductance of a magnetic structure is reduced, by making ears with cuts which converge toward the magnetic rods that are used in the formation of the structure.
