In this context, integrated circuits proved to be a viable solution with high associated nonrecurring costs and design risks. As an alternative, this article presents a fully autonomous and battery-less circuit solution for piezoelectric energy harvesting based on discrete components in a low-cost PCB technology, which achieves a comparable performance in a 32 \u00d7 43 mm\n            <jats:sup>2<\/jats:sup>\n            footprint. The power management circuit implements synchronous electric charge extraction (SECE) with a passive bootstrap circuit from fully discharged states. Circuit characterization showed that the circuit consumes less than 1\u03bc A with a 3V output and may achieve energy conversion efficiencies of up to 85%. In addition, the circuit is specifically designed for operating with input and output voltages up to 20V, which grants a significant flexibility in the choice of transducers and energy storage capacitors.\n          <\/jats:p>","DOI":"10.1145\/2700244","type":"journal-article","created":{"date-parts":[[2015,8,4]],"date-time":"2015-08-04T13:57:39Z","timestamp":1438696659000},"page":"1-17","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["A Sub-\u03bc A Stand-By Current Synchronous Electric Charge Extractor for Piezoelectric Energy Harvesting"],"prefix":"10.1145","volume":"12","author":[{"given":"Aldo","family":"Romani","sequence":"first","affiliation":[{"name":"University of Bologna"}]},{"given":"Matteo","family":"Filippi","sequence":"additional","affiliation":[{"name":"University of Bologna"}]},{"given":"Michele","family":"Dini","sequence":"additional","affiliation":[{"name":"University of Bologna"}]},{"given":"Marco","family":"Tartagni","sequence":"additional","affiliation":[{"name":"University of Bologna"}]}],"member":"320","published-online":{"date-parts":[[2015,8,3]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"crossref","unstructured":"S.
