These dimensions include the trench width and depth, cable depth and diameter, and thickness of the top layer. The dimensions, such as the trench width and the cable diameter, are varied to emphasize their effect on the heat dissipation. A simple model using the finite difference technique is used to determine the temperature at each node of the grid, and the Gauss-Siedel iteration method is used to solve the temperature equations. The heat dissipation from buried cables can be increased either by using larger cable diameter or by increasing the width of the trench. The number of grid points has a remarkable influence on the predicted value of heat dissipation. The percentage of the change in the heat dissipation due to the diameter or the trench width remains approximately the same for various grid points. The heat balance analysis shows that the difference between the cable heat dissipation and the heat losses from the grid boundaries is less than 0.3%, and the convective surface at the grid top plays a major role in dissipating the heat produced by the cable by almost 86% for most of the trenches with various widths.<<ETX>>","PeriodicalId":6453,"journal":{"name":"[1991] Proceedings of the 34th Midwest Symposium on Circuits and Systems","volume":"14 1","pages":"743-747 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1991-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76799238","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 technique is shown to be highly efficient of both in terms silicon area consumption and time. More interestingly, it is shown that the operation delay is almost independent of the word size, and hence the method is best used for high-density codes. Structurally, the circuit is made of two parallel paths: one for the input data and one for the generation of the control signal to be utilized for DIT operation through the data path. The circuit is designed and simulated for 64-bit word length using CMOS technology. For the worst-case situation, a 14.7 ns response time is reported.<<ETX>>","PeriodicalId":6453,"journal":{"name":"[1991] Proceedings of the 34th Midwest Symposium on Circuits and Systems","volume":"80 1","pages":"887-890 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1991-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80970607","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 advantages obtained using this approximation when compared to the Thomson approximation include the fact that the group delay can be varied by varying one of the two parameters available, and in the stopband the magnitude may or may not approach zero as frequency increases. This class of low-pass linear phase transfer functions gives a magnitude which has quasi-maximally flat magnitude. The function has several parameters that allow the function to change the slope in the phase function, the slope in the transition band, the cut-off frequency, and the magnitude value at infinite frequency.<<ETX>>","PeriodicalId":6453,"journal":{"name":"[1991] Proceedings of the 34th Midwest Symposium on Circuits and Systems","volume":"262 1","pages":"704-707 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1991-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79681160","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}
