It is important to ensure the validity of the output signals, while increasing the rate at which data may be clocked into the pipeline. This is achieved by balancing the path delays from the inputs to all intermediate nodes and outputs. Wave-domino logic uses dynamic CMOS domino circuits to implement wave-pipelining. This paper builds upon existing work in wave-domino pipelining and introduces an improved clocking strategy for such a pipeline which further minimizes the clock period, thereby increasing the system throughput.","PeriodicalId":68559,"journal":{"name":"电路与系统学报","volume":"83 12","pages":"1832-1835 vol.3"},"PeriodicalIF":0.0,"publicationDate":"1997-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/ISCAS.1997.621503","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72484466","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}

This result is based on a quadratic storage function plus integral term. For nonlinear modelling and control purposes it enables to modify the classical dynamical backpropagation algorithm with a matrix inequality constraint in order to guarantee stable identified models or stable closed-loop control schemes, in a similar fashion has this can be done in discrete time NL/sub q/ theory.","PeriodicalId":68559,"journal":{"name":"电路与系统学报","volume":"1 1","pages":"517-520 vol.1"},"PeriodicalIF":0.0,"publicationDate":"1997-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85137494","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}
