Abstract
Various implementations described herein are related to a device having a first coil-shaped spiral structure for an active shield and a second coil-shaped spiral structure that is wound in-between windings of the first coil-shaped spiral structure. The first coil-shaped spiral structure may provide for a coil-based electro-magnetic (EM) shield as a counter-measure circuit for protecting an underlying circuit.
Claims18
A device comprising:
- an array of active shield coil structures, wherein each active shield coil structure comprises:
- a first coil-shaped spiral structure for an active shield;
- and
- a second coil-shaped spiral structure that is wound in-between windings of the first coil-shaped spiral structure, wherein:
- the first coil-shaped spiral structure provides for a coil-based electro-magnetic (EM) shield as a counter-measure circuit for protecting an underlying circuit, and
- wherein the array of the active shield coil structures is arranged in a grid pattern.
