It is shown that these two spectral features outperform traditional cepstral (MFCC) features. Spectral energy in 17 bands of frequencies on Bark scale as well as 16 mel-scale warped cepstral coefficients were used independently for classifying stressed speech. The proposed features employ a neural network model based on the Levenberg-Marquardt algorithm. Their observed performance demonstrates the viability of the Bark spectral energy set in stressed speech detection experiment and classifies angry, question, and clear stressed speech conditions. Preliminary results of matching features for a small set of utterances showed correct detection of speech condition in better than 83% of the cases using each set of features from Bark band energy. Significant spectral energy and MFCC features, on the other hand, showed close to 75% correct detection for the same utterances.","PeriodicalId":216848,"journal":{"name":"2014 IEEE 12th International New Circuits and Systems Conference (NEWCAS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131566142","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}

Despite recent approaches to remove metallic CNTs from the inherent mixture of chiralities, the circuits still suffer from this issue. In consequence, the CNTFET device performance is degraded which in turn impacts the circuit yield. This paper proposes a comprehensive framework to analyze the leakage power, delay, and the manufacturing yield of circuits in the presence of metallic CNTs. With the help of our framework, the effect of different factors such as the probability of metallic tubes and the cell layout on the performance metrics is investigated. Moreover, we propose a new layout structure for standard cells to improve the overall yield of the circuit by around 10%.","PeriodicalId":216848,"journal":{"name":"2014 IEEE 12th International New Circuits and Systems Conference (NEWCAS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131811670","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}

Compressive sensing entails projecting the signal on a set of random signals, which is done by means of mixers and low pass filters. When reconstructing the signal, it is important to have a model for the sensing hardware, hence, the need to mitigate variability effects on the reconstruction process. In order to do that, there is a need for quantifying the effect of variability on reconstruction in order to be able to design compressive sensing systems that are robust to variability.","PeriodicalId":216848,"journal":{"name":"2014 IEEE 12th International New Circuits and Systems Conference (NEWCAS)","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116468162","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}

Therefore, high-level system modeling is required to reduce the simulation time and allow for effective initial design or successive iterations between system-level and transistor-level simulations. Accordingly, a precise behavioral modeling technique for radiofrequency (RF) continuous time (CT) DSM is presented. The main contribution of this work is the differential nature of the RF CT-DSM model in MATLAB such that is it suited for co-simulation in a circuit simulator environment.
