Conventional D\/A converter of M-ary circuit has been replaced with the operational transconductance amplifier-based n-bits to 2<jats:sup>n<\/jats:sup> level converter which operates with input frequencies up to 2.1 GHz. OTA-based oscillator and PLL is being designed for high speed M-ary FSK. Eye diagram analysis has been carried out, conforming a very low signal distortion. Theoretical analysis of bit error rate has been done. The circuit analysis and simulation results confirm the reliability and accuracy of the design. Effective layouts and die photographs of the proposed designs are also presented. <\/jats:p>","DOI":"10.1142\/s0218126615501522","type":"journal-article","created":{"date-parts":[[2015,9,13]],"date-time":"2015-09-13T21:45:50Z","timestamp":1442180750000},"page":"1550152","source":"Crossref","is-referenced-by-count":3,"title":["Design Methodology of High Frequency M-ary ASK, FSK and QAM"],"prefix":"10.1142","volume":"24","author":[{"given":"Mousumi","family":"Bhanja","sequence":"first","affiliation":[{"name":"Department of ETC, IIEST, Shibpur, Howrah, West Bengal 711103, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Surya Prakash","family":"Tamang","sequence":"additional","affiliation":[{"name":"Department of ETC, IIEST, Shibpur, Howrah, West Bengal 711103, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ritika","family":"Das","sequence":"additional","affiliation":[{"name":"Department of ETC, IIEST, Shibpur, Howrah, West Bengal 711103, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baidyanath","family":"Ray","sequence":"additional","affiliation":[{"name":"Department of ETC, IIEST, Shibpur, Howrah, West Bengal 711103, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2015,10,25]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1109\/81.917985"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1109\/TMTT.2012.2211381"},{"key":"rf8","doi-asserted-by":"publisher","DOI":"10.1109\/TCSII.2008.2008054"},{"key":"rf12","volume-title":"Analogue IC Design: The Current-Mode Appraoch","author":"Toumazou C.","year":"1990"},{"key":"rf13","doi-asserted-by":"publisher","DOI":"10.1049\/ip-g-2.1990.0014"},{"key":"rf17","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2004.825022"},{"key":"rf18","doi-asserted-by":"publisher","DOI":"10.1109\/19.982980"},{"key":"rf19","volume-title":"Principles of Communication Systems","author":"Taub H.","year":"2009"},{"key":"rf24","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2011.2181135"},{"key":"rf27","doi-asserted-by":"publisher","DOI":"10.1109\/TCOM.1975.1092806"}],"container-title":["Journal of Circuits, Systems and Computers"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218126615501522","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,6]],"date-time":"2019-08-06T09:20:38Z","timestamp":1565083238000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218126615501522"}},"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\/S0218126615501522"],"URL":"https:\/\/doi.org\/10.1142\/s0218126615501522","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]]}}}
