Abstract :
This paper reports on the results of an integrated rectifier for wirelessly powered medical electronic devices. To considerably enhance the rectification efficiency, high-performance active diodes are incorporated. In addition, a fine cost-effective and energy-efficient back telemetry mechanism with increased robustness against physical variations in the external reader and internal transponder (implant) has been equipped. Fabricated in a 0.18-μm technology, the design demonstrates that it is able to achieve maximum conversion efficiency approximately 90%, while at the same time dramatically reducing the overhead to practical implementation. It has also been proved for its full functionality in the asserted built-in robust back telemetry.
