Abstract

An entangled inductor structure generates opposite polarity internal magnetic fields therein to substantially reduce, or cancel, external magnetic fields propagating outside of the entangled inductor structure. These reduced external magnetic fields propagating outside of the entangled inductor structure effectively reduce a keep out zone (KOZ) between the entangled inductor structure and other electrical, mechanical, and/or electro-mechanical components. This allows the entangled inductor structure to be situated closer to these other electrical, mechanical, and/or electro-mechanical components within the IC as compared to conventional inductors which generate larger external magnetic fields.
