We also up-convert these broadband signals to millimeter-wave frequency to verify the correlation equation for 44-GHz power amplifiers. These measurement results show good agreement, within /spl plusmn/ 1 dB, between two-tone and multi-tone tests up to the P/sub 1 dB/ point. It is observed that, as the input power increased, the multi-tone ACPR has a similar trend as the ACPR for broadband signals, like WCDMA and 16-QAM in microwave and millimeter-wave frequency band.","PeriodicalId":337918,"journal":{"name":"2005 IEEE International Wkshp on Radio-Frequency Integration Technology: Integrated Circuits for Wideband Comm & Wireless Sensor Networks","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125948504","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}

While a phase locked loop (PLL) is classically brought into play whenever a frequency synthesis is needed, the design of key building blocks such as the RF frequency divider is a very challenge. Concerning the latter, the synchronized ring oscillator (SRO), which provides dual-modulus division at frequency above 20 GHz while consuming little power, is presented. Alternative solutions to the classical PLL, such as injection locked oscillator (ILO) and factorial delay locked loop (F-DLL) are presented as well. Advantages and drawbacks of these approaches are discussed, based upon simulation and experimental measurements.","PeriodicalId":337918,"journal":{"name":"2005 IEEE International Wkshp on Radio-Frequency Integration Technology: Integrated Circuits for Wideband Comm & Wireless Sensor Networks","volume":"889 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114598318","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}

The VGA is fully differential with differential output swing of 1-V/sub pp/.

The VGA also has two DC offset cancellation loops to avoid the amplification of DC offset. The output DC offset of the VGA is less than 20 mV even if an input DC offset of 40 mV is introduced to the VGA.
