ADVANCED 3D INDUCTOR STRUCTURES WITH CONFINED MAGNETIC FIELD
First Claim
1. An apparatus, comprising:
- a substrate;
an inductor residing in the substrate wherein the inductor comprises a conductive path that extends from a first terminal to a second terminal, wherein the conductive path has a shape corresponding to a two-dimensional (2D) lobe laid over a three-dimensional (3D) volume such that the inductor is configured to generate a magnetic field having magnetic field lines outside the inductor that are predominately destructive and magnetic field lines inside the inductor that are predominately constructive.

Abstract
Embodiments of an apparatus that includes a substrate and an inductor residing in the substrate are disclosed. In one embodiment, the inductor is formed as a conductive path that extends from a first terminal to a second terminal. The conductive path has a shape corresponding to a two-dimensional (2D) lobe laid over a three-dimensional (3D) volume. Since the shape of the conductive path corresponds to the 2D lobe laid over a 3D volume, the magnetic field generated by the inductor has magnetic field lines that are predominately destructive outside the inductor and magnetic field lines that are predominately constructive inside the inductor. In this manner, the inductor can maintain a high quality (Q) factor while being placed close to other components.
