These techniques are being used as the novel way to solve the faulty situation in Network on Chip (NoC). Faults in NoC arises due to big sizes of interconnects as the size of the devices were continuously reduced to cope with the communication requirement of processing elements (PE's). Due to these faults a lot of conventional fault tolerant techniques have been proposed. But all of these techniques have drawbacks of latency, less bandwidth utilization and lesser throughput. In this paper, a novel bio-inspired technique “sprouting” is proposed. Bio-inspired sprouting algorithm is based on biological brain technique which makes the algorithm robust and the NoC fault tolerant. The result shows that the bio-inspired algorithm efficiently utilizes the bandwidth and throughput, packet network latency is degrading gracefully during the network recovery from fault. The average packet network latency increases 20.51%, NoC bandwidth reduces 0.471% and throughput is drop to 37.22% during the recovery from faults.","PeriodicalId":436232,"journal":{"name":"2013 IEEE International Conference on Circuits and Systems (ICCAS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129156048","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}

A complete integrated silicon based resonator potentially eliminates lossy interfacing to on chip electronics. This paper presents the equivalent circuit modeling of a CMOS SAW resonator implemented in 0.35 μm CMOS technology. The periodic spacing of the IDTs based on the CMOS technology controls the resonance frequency of the resonator. Four different resonators at frequency range of 0.750 GHz to 1.125 GHz were simulated using MATLAB™ based on theoretical equations. High quality factors and low insertion loss is crucial to optimize the performance of the SAW resonator. Crucial design parameters such as periodic spacing, number of reflectors, array of reflectivity and coupling coefficient are highlighted. The simulated results shows high quality factor in the order of thousands and low insertion loss, which is crucial to optimize the performance of the Al doped ZnO CMOS SAW resonator.","PeriodicalId":436232,"journal":{"name":"2013 IEEE International Conference on Circuits and Systems (ICCAS)","volume":"32 3-4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132061064","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}

By using Interdigitated Electrode (IDE) structure, a sensor array for detecting mango volatile utilizing molecular imprinted polymer (MIP) as the sensing material was fabricated. Each sensor will be responsible for detecting different volatiles emitted from mango. The novel MIP sensory system able detects gases selectively through an increase in electrical capacitance when the targeted mango gases are adsorbed on the sensor's surface. Each sensor will be first be calibrated by identifying the baseline value prior inserting the mango in the chamber. Once the mango is inserted, the capacitance shift on each sensor will help to determine different mango volatiles being emitted by mango and absorb by each of the sensor. The capacitance shift will be then calculated by an interface circuit to determine the level of mango maturity ranging from non ripe, semi ripe or ripe. By having an array of such sensors, with each IDE tuned to different unique volatiles, a robust and accurate fruit maturity determination can be performed. These studies provide an interesting and alternative solution for agriculture sector to improve the quality of harvest.","PeriodicalId":436232,"journal":{"name":"2013 IEEE International Conference on Circuits and Systems (ICCAS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123591137","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}
