In this paper we present a blind adaptive method, based on the least-mean-square (LMS) algorithm, to compensate gain and timing mismatches in TIADCs. Similar to other methods in the literature, we assume a slightly oversampled input signal, but, contrary to them, we can apply our method to an arbitrary number of channels in a straightforward way. We give a detailed description of the compensation and the identification part of the method and demonstrate its effectiveness through numerical simulations.","PeriodicalId":404629,"journal":{"name":"2008 15th IEEE International Conference on Electronics, Circuits and Systems","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130333700","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 MOR is carried out on a partitioned circuit, which enables the use of low-order moments and macromodels of few elements. This benefit translates to a typical 10-100 times faster simulation with only a minimal error. The performance of the MOR method is evaluated with simulations and compared with other MOR algorithms.","PeriodicalId":404629,"journal":{"name":"2008 15th IEEE International Conference on Electronics, Circuits and Systems","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134177395","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}

Especially in the floor-planning phase, sensitive IPs should be treated as routing obstacles, which is impossible when the conventional HPWL-based method is used for routing estimation. This paper proposes an obstacle-aware minimum wiring length (MWL) estimation algorithm, based on the theoretical result in [5], through algorithmic improvements and practical approximation. The experimental results suggests that MWL-based estimation is now possible with only few times larger computational cost comparing to the HPWL-based estimation.","PeriodicalId":404629,"journal":{"name":"2008 15th IEEE International Conference on Electronics, Circuits and Systems","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134237058","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}
