We present a non-contact inductive-coupling data communication link employing a rotary data encoding scheme. The circuit consumes 50% less power and is inherently more robust to jitter than previously reported solutions. Applications include wafer-level testing, non-contact memory card interfaces and inter-strata data communication in 3D-integrated circuits.
This paper presents a non-contact memory card and a host employing simultaneous data and power transmission through inductive coupling. Nested clover-shaped data coils are proposed for reducing interference from a power link. The host wirelessly tracks current consumption of the card and adjusts transmit power to improve power transfer efficiency. The prototype is implemented in 65nm CMOS. It achieves...
This paper presents a wideband, low power, and low cost pulse-based inductive-coupling interface for wireless data transfer in high performance portable devices. General aspects of wireless links are discussed to understand the position of the inductive-coupling technique. Two applications of a pulse-based inductive-coupling interface are introduced, one is a 0.14 pJ/b inter-chip link for system-in-a-package...
