Abstract :
We present an energy harvester composed of a dipole antenna, matching network and a rectifier based on thin-film metal-oxide (amorphous Indium-Gallium-Zinc Oxide, IGZO) semiconductor Schottky diodes, operating at 868MHz. S-parameters measurements show that the integrated single IGZO Schottky diodes have a cutoff frequency over 1.8GHz at 0V bias. Large signal analysis of the integrated double-half wave rectifier shows a cut-off frequency of 1.1GHz. Our harvester generates 1.3V at 15 cm from an emitter emitting 15dBm at 868MHz.
