Abstract

This paper presents a simultaneous data and power transmission utilizing inductive-coupling interfaces for a non-contact memory card application. Nested clover coils are proposed to reduce interference from a power link. In order to maximize power transfer efficiency, the power transmitter tracks and predicts power consumption patterns of the memory card, and adjusts power transfer level. A test-chip prototype fabricated in a 65 nm CMOS process demonstrates 6 Gb/s data rate and 10% power transfer efficiency across a 0.1-2 kΩ load range.
