For same reason, this new device also exhibits a higher transconductance (GM) and its GD also maintains a good electrical performance with no kink effect compared with the conventional FinFET.

For instance, we may use it to track freights on a warehouse, to catch a thief for lost luggage and to rapidly locate lost children or passengers who fail to arrive on time at the departure gates of major airport. It can also be employed for transmitting multimedia content (especially for video). Presently, many research works focus on designing the RFID tag with high transmission data rate. In this paper we present a new practical scheme, it integrates the video surveillance into RFID tag at range of 250 kbps data rate for video data transmission. We believe that has not been addressed before in the literature. Here the Distributed Video Coding (DVC) scheme is integrated into RFID tag, where the so-called padding-based DVC scheme, proposed by us recently, is deployed. It is known that the padding-based DVC scheme has the advantages of requiring very low complexity and achieving low bit rate. Via computer simulations we show that the proposed scheme can easily work at data rate less than 250 kbps, and achieve better performance (PSNR) than the conventional approaches.","PeriodicalId":412093,"journal":{"name":"2010 International Symposium on Next Generation Electronics","volume":"160 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132219878","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}

Multifin FETs with different fin aspect ratios [AR ≡ fin height (Hfin)/fin width (Wfin)] and a fixed channel volume are simulated in a three-dimensional device simulation and the simulation results are experimentally validated. The multi-fin FinFET (AR = 2) has better channel controllability than the multifin trigate (AR = 1) and multi-fin quasi-planar (AR = 0.5) FETs. A six-transistor (6T) static random access memory (SRAM) using multi-fin FinFETs also provides the largest static noise margin because it supports the highest transconductance in FinFETs. Although FinFETs have a large effective device width and driving current, their large gate capacitance limits gate delay. The transient characteristics of an inverter with multi-fin transistors are further examined, and compared with those of an inverter with single-fin transistors. The multi-fin inverter has a shorter delay because it is dominated by the driving current of the transistor. With respect to random-dopant-induced fluctuations, the multifin FinFET suppresses not only the surface potential but also its variation because it has a more uniform surface potential than the multifin trigate and quasi-planar FET, and so the effects of random dopants on the circuits are attenuated. The results of this study provide insight into the DC, and circuit characteristics of multifin transistors and associated random dopant fluctuations.","PeriodicalId":412093,"journal":{"name":"2010 International Symposium on Next Generation Electronics","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126009596","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}
