A 14-Gb/s 4-PAM adaptive analog equalizer is proposed to compensate the 40-inch backplane interconnections by using a sum-feedback filter (SFF), relaxing the design requirement of the conventional analog feed-forward equalizers (FFE). 4-level pulse amplitude modulation (PAM) is also adopted to increase the transmission data rate over bandwidth-limited channel. The 4-PAM adaptive equalizer has been fabricated in a 0.18-mum CMOS technology, while dissipating 121 mW from a single 1.8-V power supply.","PeriodicalId":142478,"journal":{"name":"2006 IEEE Asian Solid-State Circuits Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131238491","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 compile flow of ePLX is also the simple one with the standard design environments, basically. We have verified the advantage of this architecture by programming the function module and mapping the circuits with high usage efficiency and doubling operation speed. The physical architecture of ePLX uses the divided power supply LUT and wiring resources that consists of SRAM with CMOS transfer gate switch elements.
