摘要:
Embodiments of inductive communication devices include first and second galvanically isolated IC die. The first IC die has a first coil proximate to a first surface of the first IC die, and the second IC die has a second coil proximate to a first surface of the second IC die. The first and second IC die are arranged so that the first surfaces of the first and second IC die face each other, and the first coil and the second coil are aligned across a gap between the first and second IC die. One or more dielectric components are positioned within the gap directly between the first and second coils. During operation, a first signal is provided to the first coil, and the first coil converts the signal into a time-varying magnetic field. The magnetic field couples with the second coil, which produces a corresponding second signal.

Embodiments of inductive communication devices include first and second galvanically isolated IC die and a dielectric structure. Each IC die has a coil proximate to a first surface of the IC die. The IC die are arranged so that the first surfaces of the IC die face each other, and the first coil and the second coil are aligned across a gap between the first and second IC die. The dielectric structure is positioned within the gap directly between the first and second coils, and a plurality of conductive structures are positioned in or on the dielectric structure and electrically coupled with the second IC die. The conductive structures include portions configured to function as bond pads, and the bond pads may be coupled to package leads using wirebonds. During operation, signals are conveyed between the IC die through inductive coupling between the coils.
