In the present paper, we investigate the quantum magneto-capacitance of metal-insulator-semiconductor (MIS) structures based on diluted magnetic semiconductors (DMS) in the presence of Rashba spin-orbit interaction (SOI). Typical beating patterns with well defined node-positions in the oscillating quantum capacitance are observed. A simple relation that predicts the positions of nodes in the beating patterns is obtained. The interplay between the giant Zeeman splitting (including s-d exchange interaction) and the Rashba SOI, is discussed.","PeriodicalId":391668,"journal":{"name":"2009 International Conference on Microelectronics - ICM","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":"130729597","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}

They can be made reconfigurable for improving efficiency and reliability. Constituent microsensors in such a reconfigurable array are highly desirable to operate in an ultra low power regime, have a short response time, and take as small chip area as possible. Metal oxide (MOX) materials used for detecting gaseous species usually operate at high temperatures, say, 350° C or beyond. In this work, we introduce and evaluate the use of silica aerogel as the insulating material of choice over the air gap (commonly produced by costly micromachining). Superior properties of aerogel lead to considerable reduction in power consumption and in array chip area while lowering the fabrication cost, based on our extensive simulation evaluation using IntelliSuite software. Silica aerogel is compatible with the CMOS process, ensuring a low overall production cost.","PeriodicalId":391668,"journal":{"name":"2009 International Conference on Microelectronics - ICM","volume":"80 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":"131952904","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}

One important issue which greatly affects the performance of a multicast switch is how to reduce data loss caused by blocking during the process of duplication and routing of the packets. This paper proposes a multicast crossbar switch with an inner queue at each cross point. With the proposed architecture, no additional control circuits are needed for performing duplication and self-routing. To reduce data loss, duplicated packets are first stored in the inner queues, then continue to transmit at the beginning of the next time slot. By controlling the interarrival time of two sequential groups of packets, our approach can reduce the rate of data loss to 10−6 or less. Due to simplicity of the proposed architecture, hardware implementation can be realized with ease while delivering good scalability and stackability. The proposed multicast switch has been implemented and verified on an Altera Stratix II EP2S60F1020 chip. It operates at a clock rate of 80 MHz and uses only eight percent of the available look-up tables.","PeriodicalId":391668,"journal":{"name":"2009 International Conference on Microelectronics - ICM","volume":"44 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":"115262425","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}

This approach is inspired by the game, Tetris'. The modules are selected one at a time and placed to the partial floorplan, while attempting to grow on upper, in a row-by-row manner, until all the modules are arranged to the floorplan. In each row, modules are tried to be placed without deadspace. If any row is filled up, this row is viewed as “full” and thus it is “eliminated”. The modules are sorted and constructively moved into the partial floorplan. A contour that encloses the top of the packed modules in the floorplan is constructed to help for arrangement of the modules. Experimental results on MCNC and GSRC benchmarks demonstrate that we obtain significant improvements on the area minimization and computational efforts. Particularly, our methodology provides greater improvement over other floorplanners as the number of modules increases, which is a feature of scalability.","PeriodicalId":391668,"journal":{"name":"2009 International Conference on Microelectronics - ICM","volume":"13 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":"125197180","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}

Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) being a special case of multicarrier transmission is chosen by WiMedia and EMCA International for its high bit rate capability. To meet this high bit rate requirement while keeping the peak transmitted power under the permitted limit, several bit loading algorithms have been presented in technical literature for OFDM. These algorithms are evaluated and compared on the basis of their theoretical complexity and computation efficiency. However, this theoretical complexity analysis is unable to take into account final implementation issues such as energy consumption and required chip area. In this paper, energy consumption and circuit area estimation of two popular bit-loading algorithms are analyzed in a multiobjective approach and put into evidence the need to analyze new proposals in a more global approach.","PeriodicalId":391668,"journal":{"name":"2009 International Conference on Microelectronics - ICM","volume":"39 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":"123495470","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}

With the presented sensor, object localization and position detection functions are simplified, performed at higher speeds in real time, and power requirement is reduced. The sensor in-pixel processing, filters out the background image data and detects the modulated marker regions. Object localization is facilitated by the use of distributed sensors to cover a more extended space. Since marker locations are extracted locally at each sensor, data transmission rate at each node and power demand is reduced; thus the sensor nodes can be designed as wireless and self powered units.
