As opposed to the typical oxide materials (such as Al2O3), the high electron affinity of the proposed oxide allows for the p-type charge transfer doping of the underlying diamond substrate. The comparison of the hydrogenated diamond surface with and without the V2O5 are reported jointly with the electrical performance of the optimized MISFETs and a preliminary small-signal equivalent circuit.","PeriodicalId":183218,"journal":{"name":"2016 IEEE Compound Semiconductor Integrated Circuit Symposium (CSICS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122650437","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 level-shift circuit placed between a main transimpedance amplifier and a post amplifier mitigates the trade-off between the bandwidth and noise of the receiver, which reduces the input referred noise by 70%. The DFB compensates for process variation without increasing the noise. The transimpedance amplifier was fabricated in 0.13-um SiGe BiCMOS technology and packaged with an avalanche photodiode. The 3-dB bandwidth of 38.4 GHz and the input referred noise current density of 14.8 pA/rtHz are achieved. These are the best performance among published 50-Gb/s-class transimpedance amplifiers for optical communication.","PeriodicalId":183218,"journal":{"name":"2016 IEEE Compound Semiconductor Integrated Circuit Symposium (CSICS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124919019","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 combination of the two achieves a peak output power of 4.8W, and average total efficiencies for a 6dB PAR QPSK signal of 44.1% and 48.1% with and without considering the supply modulator consumption, respectively, demonstrating the feasibility of this PA architecture with a real discrete supply modulator.","PeriodicalId":183218,"journal":{"name":"2016 IEEE Compound Semiconductor Integrated Circuit Symposium (CSICS)","volume":"58 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127578825","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}
