The Low-Power CMOS DCO is designed based on the ring oscillator implemented with Schmitt trigger inverters. The proposed DCO circuit uses control codes of thermometer type to reduce jitters. Performance of the DCO is verified through a novel All Digital Phase-Locked Loop (ADPLL) designed with a unique lock-in process by employing a time-to-digital converter, where both the frequency of the reference clock and the delay between DCO_output and DCO_clock is measured. A carefully designed reset process reduces the phase acquisition process to two cycles. The ADPLL was implemented using the 32\u2009nm Predictive Technology Model (PTM) at 0.9\u2009V supply voltage, and the simulation results show that the proposed ADPLL achieves 10 and 2 reference cycles of frequency and phase acquisitions, respectively, at 700\u2009MHz with less than 67\u2009ps peak-to-peak jitter. The DCO consumes 2.2\u2009mW at 650\u2009MHz with 0.9\u2009V power supply.<\/jats:p>","DOI":"10.1155\/2010\/946710","type":"journal-article","created":{"date-parts":[[2010,1,19]],"date-time":"2010-01-19T15:30:33Z","timestamp":1263915033000},"page":"1-11","source":"Crossref","is-referenced-by-count":12,"title":["A Low-Power Digitally Controlled Oscillator for All Digital Phase-Locked Loops"],"prefix":"10.1155","volume":"2010","author":[{"given":"Jun","family":"Zhao","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, Northeastern University, Boston, MA 02115, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong-Bin","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Northeastern University, Boston, MA 02115, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/4.753684"},{"issue":"11","key":"3","doi-asserted-by":"crossref","first-page":"1634","DOI":"10.1109\/4.726549","volume":"33","year":"1998","journal-title":"IEEE Journal of Solid-State Circuits"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/4.165341"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2002.807398"},{"issue":"5","key":"7","doi-asserted-by":"crossref","first-page":"700","DOI":"10.1109\/4.509852","volume":"31","year":"1996","journal-title":"IEEE Journal of Solid-State Circuits"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/TCSII.2004.842067"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2004.826333"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/4.375961"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/4.953487"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1109\/TCSII.2005.846307"}],"container-title":["VLSI Design"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/archive\/2010\/946710.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/archive\/2010\/946710.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/archive\/2010\/946710.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,12,9]],"date-time":"2020-12-09T07:23:53Z","timestamp":1607498633000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/vlsi\/2010\/946710\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,1,19]]},"references-count":10,"alternative-id":["946710","946710"],"URL":"https:\/\/doi.org\/10.1155\/2010\/946710","relation":{},"ISSN":["1065-514X","1563-5171"],"issn-type":[{"value":"1065-514X","type":"print"},{"value":"1563-5171","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,1,19]]}}}
