The conventional operational transconductance amplifiers (OTAs)-comparator is replaced with a Schmitt trigger to significantly reduce the delay. This Schmitt trigger is implemented by a differential structure operating in the subthreshold region to generate a proportional to absolute temperature (PTAT) hysteresis. Both the voltage reference and the current source are made PTAT as well. The proposed oscillator can be made ultra-low power and have excellent frequency stability over process, voltage and temperature (PVT) variation. <\/jats:p>","DOI":"10.1142\/s0218126615501479","type":"journal-article","created":{"date-parts":[[2015,7,29]],"date-time":"2015-07-29T01:37:35Z","timestamp":1438133855000},"page":"1550147","source":"Crossref","is-referenced-by-count":2,"title":["Relaxation Oscillator Exploiting PTAT Hysteresis of Differential Schmitt Trigger"],"prefix":"10.1142","volume":"24","author":[{"given":"Lin","family":"He","sequence":"first","affiliation":[{"name":"Micro-\/Nano-Electronic System Integration Center (MESIC), University of Science and Technology of China, Hefei 230026, Anhui, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gang","family":"Li","sequence":"additional","affiliation":[{"name":"Wisdri (Wuhan) Automation Co., Ltd, Wuhan, Hubei, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meng","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Electronic and Information Engineering, Soochow University, Suzhou, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2015,10,25]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1109\/TCSI.2009.2015208"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2008.2007438"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1109\/TCSI.2009.2016133"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2005.863149"},{"key":"rf7","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2009.2020247"},{"key":"rf8","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2010.2048732"},{"key":"rf9","doi-asserted-by":"publisher","DOI":"10.1109\/TCSI.2010.2041504"},{"key":"rf11","doi-asserted-by":"publisher","DOI":"10.1016\/S0026-2692(84)80030-0"},{"key":"rf12","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.1985.1052380"},{"key":"rf13","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.1982.1051864"}],"container-title":["Journal of Circuits, Systems and Computers"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218126615501479","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,6]],"date-time":"2019-08-06T13:20:31Z","timestamp":1565097631000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218126615501479"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,10,25]]},"references-count":10,"journal-issue":{"issue":"10","published-online":{"date-parts":[[2015,10,25]]},"published-print":{"date-parts":[[2015,12]]}},"alternative-id":["10.1142\/S0218126615501479"],"URL":"https:\/\/doi.org\/10.1142\/s0218126615501479","relation":{},"ISSN":["0218-1266","1793-6454"],"issn-type":[{"value":"0218-1266","type":"print"},{"value":"1793-6454","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,10,25]]}}}
