The proposed LDO provides a regulated 1.8 V voltage from a 3.6 V to 1.94 V battery voltage over a -40 °C to 100 °C temperature range, with a compact topology (<0.10 mm2 area) and a constant quiescent current of only 7.45 µA with 99.985% current efficiency, achieving remarkable state-of-art Figures of Merit (FoMs) for the regulating-transient 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.2018http://zaguan.unizar.es/record/7092810.3390/s18051405http://zaguan.unizar.es/record/70928oai:zaguan.unizar.es:70928info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2015-65750-Rinfo:eu-repo/grantAgreement/ES/UZ/JIUZ-2016-TEC-06Sensors (Switzerland) 18, 5 (2018), 1405 [17 pp]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
