The proposed neural recording amplifier is based on a capacitive-feedback architecture and utilizes a low-power two-stage source-degenerated operational transconductance amplifier (OTA) with a modified current buffer compensation for large open-loop gain, low-noise and wide bandwidth. The designed amplifier achieves a measured gain of 39.2[Formula: see text]dB with a bandwidth between 0.25[Formula: see text]Hz to 28[Formula: see text]kHz, integrated input referred noise of 5.79[Formula: see text][Formula: see text]Vrms and noise efficiency factor of 3.16. The IC consumes 2.4[Formula: see text][Formula: see text]W at 1.2[Formula: see text]V supply and the die area is 0.09[Formula: see text]mm<jats:sup>2<\/jats:sup>. <\/jats:p>","DOI":"10.1142\/s0218126618500688","type":"journal-article","created":{"date-parts":[[2017,8,18]],"date-time":"2017-08-18T06:16:47Z","timestamp":1503037007000},"page":"1850068","source":"Crossref","is-referenced-by-count":19,"title":["A Low-Noise Biopotential CMOS Amplifier IC Using Low-Power Two-Stage OTA for Neural Recording Applications"],"prefix":"10.1142","volume":"27","author":[{"given":"Hyung Seok","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Electrical and Information Engineering, Seoul National University of Science and Technology, 232 Gongneung-ro, Nowon-gu, Seoul 139-743, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyouk-Kyu","family":"Cha","sequence":"additional","affiliation":[{"name":"Department of Electrical and Information Engineering, Seoul National University of Science and Technology, 232 Gongneung-ro, Nowon-gu, Seoul 139-743, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2018,2,6]]},"reference":[{"key":"S0218126618500688BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2003.811979"},{"key":"S0218126618500688BIB002","doi-asserted-by":"publisher","DOI":"10.1109\/TCSI.2013.2249175"},{"key":"S0218126618500688BIB003","doi-asserted-by":"publisher","DOI":"10.1109\/TBCAS.2007.907868"},{"key":"S0218126618500688BIB005","doi-asserted-by":"publisher","DOI":"10.1109\/TCSI.2012.2230504"},{"key":"S0218126618500688BIB006","doi-asserted-by":"publisher","DOI":"10.1109\/TCSII.2005.852530"},{"key":"S0218126618500688BIB007","doi-asserted-by":"publisher","DOI":"10.1109\/TBCAS.2010.2078815"},{"key":"S0218126618500688BIB008","doi-asserted-by":"publisher","DOI":"10.1109\/TBCAS.2013.2288680"}],"container-title":["Journal of Circuits, Systems and Computers"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218126618500688","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,21]],"date-time":"2019-09-21T01:47:22Z","timestamp":1569030442000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218126618500688"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,2,6]]},"references-count":7,"journal-issue":{"issue":"05","published-online":{"date-parts":[[2018,2,6]]},"published-print":{"date-parts":[[2018,5]]}},"alternative-id":["10.1142\/S0218126618500688"],"URL":"https:\/\/doi.org\/10.1142\/s0218126618500688","relation":{},"ISSN":["0218-1266","1793-6454"],"issn-type":[{"value":"0218-1266","type":"print"},{"value":"1793-6454","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,2,6]]}}}
