The proposed amplifier is based on the true piecewise linear function by using progressive-compression parallel-summation architecture. A DC offset cancellation feedback loop is used to prevent output saturation and deteriorated input sensitivity from inherent DC offset voltages. The proposed logarithmic amplifier was designed and fabricated in a standard 0.18[Formula: see text][Formula: see text]m CMOS technology. The prototype chip includes six limiting amplifier stages and an on-chip bias generator, occupying a die area of 0.027[Formula: see text]mm<jats:sup>2<\/jats:sup>. The overall circuit consumes 9.75[Formula: see text][Formula: see text]W from a single 1.5[Formula: see text]V power supply voltage. Measured results showed that the prototype logarithmic amplifier exhibited an 80[Formula: see text]dB input dynamic range (from 10[Formula: see text][Formula: see text]V to 100[Formula: see text]mV), a bandwidth of 4[Formula: see text]Hz\u201310[Formula: see text]kHz, and a total input-referred noise of 5.52[Formula: see text][Formula: see text]V. <\/jats:p>","DOI":"10.1142\/s0218126618501049","type":"journal-article","created":{"date-parts":[[2017,11,1]],"date-time":"2017-11-01T08:48:35Z","timestamp":1509526115000},"page":"1850104","source":"Crossref","is-referenced-by-count":7,"title":["A Low-Noise, Low-Power, Wide Dynamic Range Logarithmic Amplifier for Biomedical Applications"],"prefix":"10.1142","volume":"27","author":[{"given":"Yuwadee","family":"Sundarasaradula","sequence":"first","affiliation":[{"name":"Faculty of Engineering, King Mongkut\u2019s Institute of Technology Ladkrabang, Chalongkrung Road, Bangkok 10520, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Apinunt","family":"Thanachayanont","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, King Mongkut\u2019s Institute of Technology Ladkrabang, Chalongkrung Road, Bangkok 10520, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2018,3,26]]},"reference":[{"key":"S0218126618501049BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2002.803059"},{"key":"S0218126618501049BIB002","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2005.848023"},{"key":"S0218126618501049BIB003","doi-asserted-by":"publisher","DOI":"10.1109\/TSA.2004.841044"},{"key":"S0218126618501049BIB004","doi-asserted-by":"publisher","DOI":"10.1109\/TBME.2008.2007850"},{"key":"S0218126618501049BIB005","doi-asserted-by":"publisher","DOI":"10.1002\/cta.1861"},{"key":"S0218126618501049BIB007","doi-asserted-by":"publisher","DOI":"10.1109\/TIM.2014.2371191"},{"key":"S0218126618501049BIB011","doi-asserted-by":"publisher","DOI":"10.1049\/el.2011.0338"},{"key":"S0218126618501049BIB012","doi-asserted-by":"publisher","DOI":"10.1007\/s10470-011-9820-5"},{"key":"S0218126618501049BIB015","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2003.811979"},{"key":"S0218126618501049BIB016","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.1987.1052869"},{"key":"S0218126618501049BIB017","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2011.2163552"},{"key":"S0218126618501049BIB018","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2011.2108770"},{"key":"S0218126618501049BIB019","doi-asserted-by":"publisher","DOI":"10.1109\/TBCAS.2011.2181842"},{"key":"S0218126618501049BIB020","doi-asserted-by":"publisher","DOI":"10.1109\/TBCAS.2013.2273617"},{"key":"S0218126618501049BIB021","doi-asserted-by":"publisher","DOI":"10.1016\/j.mejo.2015.03.013"},{"key":"S0218126618501049BIB022","doi-asserted-by":"publisher","DOI":"10.1016\/j.mejo.2016.04.008"}],"container-title":["Journal of Circuits, Systems and Computers"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218126618501049","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,6]],"date-time":"2019-08-06T13:30:31Z","timestamp":1565098231000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218126618501049"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,3,26]]},"references-count":16,"journal-issue":{"issue":"07","published-online":{"date-parts":[[2018,3,26]]},"published-print":{"date-parts":[[2018,6,30]]}},"alternative-id":["10.1142\/S0218126618501049"],"URL":"https:\/\/doi.org\/10.1142\/s0218126618501049","relation":{},"ISSN":["0218-1266","1793-6454"],"issn-type":[{"value":"0218-1266","type":"print"},{"value":"1793-6454","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,3,26]]}}}
