The antenna shows dual resonance. The resonance frequency of single layer patch is found to be 2.91 GHz and 3.88 GHz which increases for two layer dielectric antenna 4.17GHz and 5.78GHz. The frequency ratio is found to be 1.33 for single layer patch antenna and 1.38 for two layer dielectric patch antenna. In general the frequency ratio is found to depend on slot length, slot width and slot angle. The band width of single layer patch antenna is found to be 1.71% and 1.68 % for lower and upper resonance frequency while it increases for two layer dielectric 5.28 % and 2.77 %. The theoretical results are compared with the simulated results obtained from IE3D and they are in close agreement.","PeriodicalId":149384,"journal":{"name":"2009 International Conference on Emerging Trends in Electronic and Photonic Devices & Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116235029","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 objects of this paper are to use a voltage difference between the two gates to screen the drain voltage and therefore reduce short channel effects (SCEs). In this transistor the surface potential exhibits a step function, which causes the screening of the drain potential. This results in suppressed SCEs such as the hot-carrier effect and decreasing off-current with respect to shrinking of channel length. The obtained results of our transistor are compared to single gate (SG) SOI MOSFET that shows the DG SOI MOSFET performance is superior. The transistor has been simulated by SILVACO software.","PeriodicalId":149384,"journal":{"name":"2009 International Conference on Emerging Trends in Electronic and Photonic Devices & Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125976826","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}

Consequently, ORGAs with more than tera-gate capacity will be realized by exploiting the storage capacity of a holographic memory. However, in contrast to current field-programmable gate arrays (FPGAs), conventional ORGAs have an important shortcoming: they are not reprogrammable after fabrication because, to reprogram ORGAs, a holographic memory must be disassembled from its ORGA package and reprogrammed outside of the ORGA package using a holographic memory writer. Then it must be implemented onto the ORGA package with high precision beyond the capability of manual assembly. To remove that problem, this paper presents a new programmable optically reconfigurable gate array and its lens-less imaging holographic memory writer system. Furthermore, this paper presents discussion of the availability of this architecture and future plans based on experimental results.","PeriodicalId":149384,"journal":{"name":"2009 International Conference on Emerging Trends in Electronic and Photonic Devices & Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125981411","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}
