First Claim
Patent Images
1. An interface for through-chip coupling of an antenna and an analog amplifier circuit, the interface comprising:
- a first coil on a first integrated circuit (IC) chip, wherein the first coil is coupled to an antenna; and
a second coil on a second IC chip, wherein the second coil is not in direct contact with the first coil, and wherein the second coil is coupled to a first amplifier circuit, and wherein the first coil and the second coil communicatively transmit signals between the antenna and the first amplifier circuit.

Abstract
Through-chip coupling is utilized for signal transport, where an interface is formed between a first coil on a first integrated circuit (IC) chip and a second coil on a second IC chip. The first coil is coupled to an antenna. The second coil is coupled to an amplifier circuit. The second coil is not in direct contact with the first coil. The first coil and the second coil communicatively transmit signals between the antenna and the first amplifier circuit.
