The presented AFE can be reconfigured for use in electropotential, bioimpedance, electrochemical, and photoelectrical modes. The advanced healthcare services based on multiparameter physiological biosignals can be easily implemented with these multimodal and highly reconfigurable features of the proposed system. The reconfigurable gain and input referred noise of the core instrumentation amplifier block are 25 dB to 52 dB, and 1 \u03bcVRMS, respectively. The power consumption of the analog blocks in one readout channel is less than 52 \u03bcW. The reconfigurable capability among various modes of applications including electrocardiogram, blood glucose concentration, respiration, and photoplethysmography are shown experimentally.<\/jats:p>","DOI":"10.3390\/s16122002","type":"journal-article","created":{"date-parts":[[2016,11,25]],"date-time":"2016-11-25T08:18:15Z","timestamp":1480061895000},"page":"2002","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Reconfigurable Multiparameter Biosignal Acquisition SoC for Low Power Wearable Platform"],"prefix":"10.3390","volume":"16","author":[{"given":"Jongpal","family":"Kim","sequence":"first","affiliation":[{"name":"Samsung Electronics Inc., Suwon 16678, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5348-3585","authenticated-orcid":false,"given":"Hyoungho","family":"Ko","sequence":"additional","affiliation":[{"name":"Department of Electronics Engineering, Chungnam National University, Daejeon 34134, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,11,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1321","DOI":"10.1109\/JSEN.2014.2370945","article-title":"Wearable sensors for human activity monitoring: A review","volume":"15","author":"Mukhopadhyay","year":"2015","journal-title":"IEEE Sens.
