The proposed LDO provides a regulated 1.8 V voltage from a 3.6 V to 1.94 V battery voltage over a \u221240 \u00b0C to 100 \u00b0C temperature range, with a compact topology (&lt;0.10 mm2 area) and a constant quiescent current of only 7.45 \u03bcA with 99.985% current efficiency, achieving remarkable state-of-art Figures of Merit (FoMs) for the regulating\u2013transient performance. Experimental measurements validate its suitability for the target application, paving the way towards the future achievement of a truly portable System on Chip (SoC) platform for impedance sensors.<\/jats:p>","DOI":"10.3390\/s18051405","type":"journal-article","created":{"date-parts":[[2018,5,3]],"date-time":"2018-05-03T03:20:27Z","timestamp":1525317627000},"page":"1405","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["A 0.18 \u03bcm CMOS LDO Regulator for an On-Chip Sensor Array Impedance Measurement System"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8617-5703","authenticated-orcid":false,"given":"Jorge","family":"P\u00e9rez-Bail\u00f3n","sequence":"first","affiliation":[{"name":"Group of Electronic Design, Aragon Institute for Engineering Research, I3A, University of Zaragoza, 50009 Zaragoza, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4949-1539","authenticated-orcid":false,"given":"Alejandro","family":"M\u00e1rquez","sequence":"additional","affiliation":[{"name":"Group of Electronic Design, Aragon Institute for Engineering Research, I3A, University of Zaragoza, 50009 Zaragoza, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bel\u00e9n","family":"Calvo","sequence":"additional","affiliation":[{"name":"Group of Electronic Design, Aragon Institute for Engineering Research, I3A, University of Zaragoza, 50009 Zaragoza, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5380-3013","authenticated-orcid":false,"given":"Nicol\u00e1s","family":"Medrano","sequence":"additional","affiliation":[{"name":"Group of Electronic Design, Aragon Institute for Engineering Research, I3A, University of Zaragoza, 50009 Zaragoza, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,5,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"14467","DOI":"10.3390\/s121114467","article-title":"Interface Design for CMOS-Integrated Electrochemical Impedance Spectroscopy (EIS) Biosensors","volume":"12","author":"Manickam","year":"2012","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Li, H., Liu, X., Li, L., Mu, X., Genov, R., and Mason, A.J.
