Contactless communications using ferromagnetic material
Abstract:
A communications structure comprises a first semiconductor substrate having a first coil, and a second semiconductor substrate having a second coil above the first semiconductor substrate. Inner edges of the first and second coils define a boundary of a volume that extends below the first coil and above the second coil. A ferromagnetic core is positioned at least partially within the boundary, such that a mutual inductance is provided between the first and second coils for wireless transmission of signals or power between the first and second coils.
