MAGNETIC CORE WITH HARD FERROMAGNETIC BIASING LAYERS AND STRUCTURES CONTAINING SAME
A planar magnetic core includes multiple ferromagnetic layers including multiple hard ferromagnetic bias layers and multiple soft ferromagnetic layers. Each ferromagnetic layer comprises a soft ferromagnetic layer or a hard ferromagnetic bias layer.

Each ferromagnetic layer has an easy axis of magnetization parallel to a principal plane of the planar magnetic core, where the easy axes of magnetization are aligned. Each hard ferromagnetic bias layer is magnetized to create an in-plane bias magnetic flux through the hard ferromagnetic bias layer in a first direction that is parallel to the easy axis of magnetization and forms a closed path through a neighboring soft ferromagnetic layer in a second direction parallel to the first direction.

Method of Generating Novel Air Gap Layouts for Laminated Magnetic Core Miniature Thin Film Inductors and Transformers with a Continuous Function
The present invention comprises a specially designed means of air gap optimization for magnetically permeable material used in electrical components, for example, inductors and transformers. First, an ideal inductance over current curve is selected, and a core start point, endpoint, start angle, and end angle are selected within the core or along the core edges. Given the ideal curve and the starting conditions, an air gap is designed which meets or comes as close as possible to the ideal curve selected. Multiple air gaps can be designed in a single core. The inclusion of novel partial air gaps enables curves to be reached that optimize the core for high and low currents.

According to one configuration, an inductor device comprises core material and at least a first electrically conductive path. The core material is fabricated from magnetically permeable material. The first electrically conductive path extends axially through the core material from a proximal end of the inductor device to a distal end of the inductor device. The core material is operable to confine first magnetic flux generated from first current flowing through the first electrically conductive path. The inductor device further includes a gap in the core material. The gap (gas or solid material) has a different magnetic permeability than the core material. Inclusion of the gap in the core material provides a way to tune an inductance of the inductor device and increase a magnetic saturation level of the inductor device. The core material includes any number of electrically conductive paths and corresponding gaps.
