A dynamic IA that can reduce power consumption with a timely piecewise power-gating method, and noise level with an alternating input and chopper stabilization technique is fabricated with a 0.13-\u03bcm CMOS. Using the reconfigurable architecture of the IA, various combinations of the low-noise schemes are investigated. The combination of power gating and chopper stabilization shows a lower noise performance than the combination of power gating and alternating input switching scheme. This dynamic IA achieved a power reduction level of 50% from 10 \u00b5A to 5 \u00b5A and a noise reduction of 90% from 9.1 \u00b5Vrms to 0.92 \u00b5Vrms with the combination of the power gating and chopper stabilization scheme.<\/jats:p>","DOI":"10.3390\/s16030354","type":"journal-article","created":{"date-parts":[[2016,3,9]],"date-time":"2016-03-09T10:38:02Z","timestamp":1457519882000},"page":"354","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["A Dynamic Instrumentation Amplifier for Low-Power and Low-Noise Biopotential Acquisition"],"prefix":"10.3390","volume":"16","author":[{"given":"Jongpal","family":"Kim","sequence":"first","affiliation":[{"name":"Samsung Electronics Inc., Suwon 16678, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5348-3585","authenticated-orcid":false,"given":"Hyoungho","family":"Ko","sequence":"additional","affiliation":[{"name":"Department of Electronics, Chungnam National University, Daejeon 34134, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2016,3,9]]},"reference":[{"key":"ref_1","unstructured":"Shin, K., Park, G., Kim, J., Lee, T., Ko, B., and Kim, Y.
