A power line transceiver demonstrates half duplex spiking communication at 135 Mbps. On-chip power line LC low pass filter attenuates pseudo-differential communication spikes by more than 30 dB, purifying power supply current for internal circuits. Chip-to-chip power line communication invokes supplementary diagnosis functionality to be embedded in SoCs at the time of power connection, with the reduced cost of pin counts.","PeriodicalId":143173,"journal":{"name":"2008 IEEE Asian Solid-State Circuits Conference","volume":"288 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127556149","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}
