The scenario gets more complicated as the channel length shrinks to deca-nanometer range and quantum mechanical effect comes into picture. In this paper, a quantum analytical threshold voltage roll-off and DIBL model for Dual Material Double Gate (DMDG) MOSFET is presented for the first time. Our expressions are derived by using effective-doping model, while incorporating quantum mechanical effects and SCEs. Variation of the quantum threshold voltage with silicon film thickness is studied for different values of work functions of front gate materials. Based on this quantum threshold voltage model, the DIBL characteristics are obtained for DMDG SON MOSFET. The sub-exponential dependence of the threshold voltage roll-off on channel length is also observed with silicon film thickness variation.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130539493","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 proposed inverter can generate 7 levels with only one DC source. By series charging and parallel discharging of capacitors, it can self balance the voltage across the two capacitors. The proposed topology incurs a lower part count compared to existing (conventional) topologies and can self balance the voltage across capacitors without any extra balancing circuit with simple control strategy. Because of high frequency coupled inductors, the dead band between some of the power switches can be eliminated and output voltage distortion is low. A 1200W power rating system has been simulated to verify the viability of the proposed topology and the relevant simulation waveforms are included.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115344064","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 proposed scheme makes use of texture features obtained using Discrete Wavelet Transform (DWT) and multiple classifiers to obtain the initial decisions on the input image. The decisions obtained from all the classifiers are fused to obtain the final decision on the input pattern. The method is tested on a private database containing HRCT images belongs to four ILDs patterns (viz. consolidation, emphysema, ground glass, nodular) and normal lung tissue. The performance of the method is compared with its single classifier based counterpart and found to be superior.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132317298","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}

On the introduction of an annular ring in between the symmetrical L-slotted patch the resonance frequency is reduced by 29.91% when edge-fed or microstrip-line feed technique is used. The coaxial feed results in dual band operation of the antenna (in C-band and X-band).

First, a model for the RFID system in both single and multiple tag environments is presented. Then, an analytical constant modulus algorithm (ACMA) for the blind source separation problem is reviewed. An alternative approach to the traditional ACMA using joint diagonalization is considered. Finally, both the ACMAs are applied to the multiple-tag RFID environment and performance of the system is studied. Simulations are carried out for 4-QAM and 16-QAM modulations at tag and analyses of the simulation results reveal that the ACMA with joint diagonalization takes lesser CPU time to execute compared to the traditional ACMA, but with higher average modulus error (AME). The variation of system performance with the number of measurements, SNR (signal to noise ratio), number of tags and number of antennas at the reader is also studied. Based on these, some design guidelines are presented. Interestingly both the ACMA algorithms work for the 16-QAM case and yield trends similar to those of 8-PSK and 4-QAM.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130426593","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}

Comparator is the basic building block of the ADCs which compares the two set of variables and change the input analog signal in digital. In this paper a new design of double tail comparator is proposed for high frequency of data conversion and is compared with the best available recently proposed double tail comparator design in term of area on chip power utilization, delay consideration and PDP. For a frequency higher than 350 MHz the power consumption is less for the proposed double tail comparator design, which keeps on getting better with every rising frequency. The maximum frequency of operation is also increased from 1.7 GHz to 2.5 GHz along with lesser delay which is significant considering the need of high speed devices.
