Abstract

In this paper, we present for the first time a novel optimization procedure which allows to maximize the efficiency of RF-DC energy harvester converters, taking into account the contributions of the matching network. Thanks to this procedure, we have designed and realized a CMOS RF-DC converter operating in a very wide range of input power -14÷+1dBm with a peak efficiency of 45% The RF-DC converter provides a constant output voltage ~2V in the whole input power range thanks to a smart voltage regulator integrated with the converter.
