The circuit has a single-ended output which avoids the use of any balun. The total power consumption in both the mixer and the output stage is only 22 mW. The signal to distortion ratio has been measured to be more than 30 dB. A thorough analysis of the harmonics caused by the nonlinearity of the mixer transistors is performed. The theory is confirmed by the measurements on the presented circuit. The chip has been processed in 0.4 /spl mu/m CMOS technology.","PeriodicalId":111737,"journal":{"name":"Proceedings of CICC 97 - Custom Integrated Circuits Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129692421","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 implementation features all major analog signal processing blocks on chip with a minimum number of offchip passive components. A PLL is used to provide transmit clocks as well as to center four pairs of gated VCOs for data synchronization. A 1st-order adaptive equalizer is designed to provide proper high-frequency boosting for different lengths of connecting cables. A current-mode filter with direct current amplification is used to provide output pulse shaping to conform 25.6 Mbps ATM output waveform templates. The power dissipation is measured at 1.3 W (325 mW per channel) during full operation of all 4 channels.","PeriodicalId":111737,"journal":{"name":"Proceedings of CICC 97 - Custom Integrated Circuits Conference","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130219129","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}

In contrast to conventional models that bypass the PLL function, this Verilog model accurately represents all major characteristics of a PLL.

It produces a clock detect signal after a realistic lock sequence. The user has the option to add jitter to the PLL output.
