Results show that the clock slope requirement can be relaxed at the cost of a very small speed penalty and energy increase in the flip-flops (FFs). On the other hand, relaxing the clock slope specification allows for downsizing the local buffers driving the FFs that belong to the same clock domain. From the energy point of view, an optimum clock slope is found that leads to energy savings of 30 ÷ 40% compared to the usually adopted clock slopes. The effectiveness of the clock slope optimization, including the impact on local skew/jitter sources, is discussed for the typical case of Master-Slave FFs by resorting to simulations on a 65-nm CMOS technology.","PeriodicalId":343974,"journal":{"name":"2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009)","volume":"219 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":"115973226","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}

However, this is a time-consuming and error-prone task. We present a novel layout exploration methodology to design arithmetic circuits using standard-cell techniques, that retains competitive performance while allowing an almost custom-design kind of control over the layout. It uses an unconventional approach with a Haskell-based front-end in the Wired system, designed to produce logically and topologically accurate circuit descriptions and at the same time be parameterizable. Further, another overall goal of the system was to keep implementation time as low as possible. We demonstrate this methodology on HPM multipliers that exhibit a high degree of layout regularity.","PeriodicalId":343974,"journal":{"name":"2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009)","volume":"150 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":"122763235","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 tangent/cotangent converter, used with these transducers to extract θ from these signals, is based on the determination of a ratio between the absolute values of the sine and cosine signals. This produces highly non-linear output. In conventional converters, θ is determined from the output using a look up table or a processor. In this work, an analog shaping network is described for the linearization of this output and hence for linear determination of θ. The optimal break points positions of the shaping network are determined experimentally and automatically using a LabVIEW-based setup that seeks minimization of the overall absolute error of the converter. The absolute error was 0.14° over the full 360° range of input angle. The principle of operation, full circuit details, computer simulation and practical results are given.","PeriodicalId":343974,"journal":{"name":"2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009)","volume":"29 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":"125678287","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, noise associated with the operation of the device could not be avoided, prior to every transmission of aroma information. Moreover, as the aroma source was located inside or in the bottom of the device, it had a problem of odor components adhering to the device structure. In this research, we focus on a chemical container of temperature responsive hydrogel, which can have reversible phase transition between sol and gel, and controlled release of aroma by using a peltier module to control the temperature. With this approach, a soundless olfactory display was achieved. In addition, we tried to solve the problem of odor component adhesion by arranging a card-based aroma source on the top of the olfactory display. Having evaluated the usability of the card-based olfactory display, we were able to confirm its effectiveness and efficiency.","PeriodicalId":343974,"journal":{"name":"2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009)","volume":"423 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":"117352791","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}
