We examine the influence of channel length (Lg) and channel thickness (Tsi) on device performance of nanoscale Double Gate (DG) MOSFETs, employing Non-equilibrium Green's function (NEGF) formalism. When the channel length is shrinks down, the electrostatic controllability of the gate over the channel decreases due to the increased charge sharing from source/drain. The present work provides design insights into the performance of nanoscale DG-MOSFET devices with optimal channel engineering and serves as a tool to optimize important device and technological parameters for 10–24′nm range.","PeriodicalId":149384,"journal":{"name":"2009 International Conference on Emerging Trends in Electronic and Photonic Devices & Systems","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123955597","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}

Carry free arithmetic operations can be achieved using a higher radix number system such as Quaternary Signed Digit (QSD). We proposed fast adders based on Quaternary signed digit number system. In QSD, each digit can be represented by a number from −3 to 3. Carry free addition and other operations on a large number of digits such as 64, 128, or more can be implemented with constant delay and less complexity. The design of these circuits is carried out using FPGA tools. The designs are simulated using modelsim software and synthesized using Leonardo Spectrum.","PeriodicalId":149384,"journal":{"name":"2009 International Conference on Emerging Trends in Electronic and Photonic Devices & Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128609058","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}

Moreover, magnetic SWG structures show wider photonic band gaps in comparison to normal magnetic PC structure for the same contrast in the wave impedance.","PeriodicalId":149384,"journal":{"name":"2009 International Conference on Emerging Trends in Electronic and Photonic Devices & Systems","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116688214","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}

It is found that the un-illuminated GaN IMPATT is capable of delivering a RF power of 5.6 W with an efficiency of 23.5% at 145.0 GHz. Frequency up-chirping of 6.0 GHz and a degradation of RF power output by almost 15.0 % are further observed in case of photo-illuminated FC IMPATT. The study reveals that compare to pre-dominate electron photocurrent in Top-Mounted IMPATT, photo-generated leakage current dominated by hole in Flip-Chip IMPATT has more pronounced effect on the GaN based device as regards the frequency chirping and decrease of negative conductance and total negative resistance per unit area of the device. The inequality in the magnitudes of electron and hole ionization rates in the Wide Band Gap semiconductor have been found to be correlated with the above results. The study reveals that GaN IMPATT is a potential candidate for replacing conventional IMPATTs at high frequency operation.","PeriodicalId":149384,"journal":{"name":"2009 International Conference on Emerging Trends in Electronic and Photonic Devices & Systems","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115448566","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}
