We use Perlin Elmer 9500 spechtrophotometer in order to measure the optical transmission and reflection. The prepared films using oxygen pressure PO2 above 3 ∗ 10<sup>−7</sup> Torr, presents a R(3) symmetry structure. The prepared samples present a deficiency δ = 0.35. The optical properties show a very important dependence with the oxygen cation stoichiometry. These last properties, which are dominated by the oxygen deficiency obtained during the growth of thin films, show a semiconductor behavior where the conductivity increase more with S than by the atomic ordering of titanium.","PeriodicalId":115975,"journal":{"name":"2017 29th International Conference on Microelectronics (ICM)","volume":"173 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133652208","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}

Most SAT solvers rely on software implemented tree-search based algorithms. These algorithms, basically sequential or weakly parallel, are most often ineffective when dealing with large scale instances of SAT due to the large search space to be explored in order to find one solution. Despite several improvements and heuristics being proposed for this kind of approach, the fact remains that in real problems, the computational cost continues to be prohibitive. To improve SAT solvers performance, a new trend has emerged in the late years, introducing hardware acceleration. The proposed architectures are in general hybrid, combining software and hardware parts dedicated respectively to the decisional and hard-computional parts of the algorithm. Still, most the hybrid approaches remain constrained by their limited data-access bandwith capacity. In this paper, we propose a new approach, entirely based on hardware and not depending on the SAT-instance to be solved (treated as data). It is fully configurable at synthesis in regard to the level of parallel computation and parallel buffering, as to the size of the SAT instance that can be processed (maximal number of variables and maximal clause length, the total number of clauses being unlimited). One of the main goals is to allow a more effective use of the hardware computational power by reducing the dependence to data contained in low bandwith data storage (such as RAM).","PeriodicalId":115975,"journal":{"name":"2017 29th International Conference on Microelectronics (ICM)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117220300","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 pass-band covers all the four bands of brain wave and, with a bandwidth of 2.17 kHz, enables a deep study of the frequencies of less interest. Besides that, a capacitor programmable circuit makes the filter possible to reject with more than 90 dB the powerline interference for 50 Hz or 60 Hz. The notch filter employs operational transconductance amplifiers working in the weak region, with transconductance of 1.259 nA/V, enabling the use of small capacitors for on-chip integration. In this project, we designed a circuit in 0.13 μm CMOS technology, for a 1.0 V power supply and 10 nA bias current. Simulations conducted on CADENCE (Virtuoso Analog Design Environment) show good performance of the filter for filtering the noise in acquired EEG signals.","PeriodicalId":115975,"journal":{"name":"2017 29th International Conference on Microelectronics (ICM)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116999922","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}
