  • Abstract
    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 6Gb/s data rate and almost 10% power transfer efficiency over a 100-2kΩ range of the load.
