The root cause of this issue is the improper timing of oscillator tuning word update with respect to the digitally-controlled oscillator (DCO) capacitor state. Using the built-in self test (BIST) circuit in the all-digital PLL (ADPLL), the DCO tuning word update timing is calibrated such that the impact on the phase noise is compensated and desired modulated spectrum margin from the specification is achieved","PeriodicalId":244429,"journal":{"name":"2006 IEEE Dallas/CAS Workshop on Design, Applications, Integration and Software","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128700167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
