The proposed approach is based on the use of appropriate diakoptics of the various circuit blocks into a matched environment, and their behavioral modeling in the fundamental-frequency dynamical complex envelope domain with the help of standard circuit and E.M. simulation CAD tools. This will permit, in the end, to obtain closed-form expressions for the main TILO performances in terms of the design parameters, thus permitting their optimization as a function of system-level specifications. The practical validity of the method developed was tested by designing and building a single transistor 10.75GHz core-TILO with a wide locking bandwidth (>4MHz) at the low nominal input power level targeted (−20dBm).","PeriodicalId":442381,"journal":{"name":"2010 XIth International Workshop on Symbolic and Numerical Methods, Modeling and Applications to Circuit Design (SM2ACD)","volume":"301 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121270384","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, most techniques reported so far to generate the fronts neglect the effect of the surrounding circuitry (such as the output load impedance) on the Pareto-front, thereby making it only valid for the context where the front was generated. This strongly limits its use in hierarchical analog synthesis because of the heavy dependence of key performances on the surrounding circuitry, but, more importantly, because this circuitry remains unknown until the synthesis process. We propose a new technique to generate the trade-off fronts that is independent of the load that the circuit has to drive. This idea is exploited for a Miller operational amplifier, and experimental results show that this is a promising approach to solve the issue.","PeriodicalId":442381,"journal":{"name":"2010 XIth International Workshop on Symbolic and Numerical Methods, Modeling and Applications to Circuit Design (SM2ACD)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131655373","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}
