Abstract

A 13.56 MHz wireless power and data transfer (WPDT) system for implantable voltammetry sensor is presented. With the synchronized phase-shifted time-multiplexing technique, the system uses a single power link to support simultaneous power and two types of data transmission via dual-uplinks with neither additional coils nor efficiency degradation. The single-power-link operation is verified in silicon, measuring a 60% peak end-to-end efficiency, a fast dynamic response, and a$>99.9 \%$data linearity.
