Although several computer-aided analysis tools are available they are not effectively used because there is a lack of understanding about their features and limitations. This paper attempts to explain the simulator-specific terminology without resorting to mathematical details. The shortcomings of conventional SPICE-like simulators and the analyses required for RF applications are described. Various analysis methods that are currently available for RF simulation are presented and commercial simulators are compared in terms of their functionalities and limitations.","PeriodicalId":111737,"journal":{"name":"Proceedings of CICC 97 - Custom Integrated Circuits Conference","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116797460","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}

It is shown that a single-ended system based on any type of op amps (rail-to-rail, constant g/sub m/, etc.), realized in any technology (CMOS, bilpolar, BiCMOS, GaAs), can be easily and effectively converted to its FB counterpart in a very practical way. Using the proposed rules, any FB system implementation with op amps (data converter, modulator, filter, etc.) requires only a single-ended system version design and the drawbacks related to a conventional FB system design are avoided. A final schematic/layout of a FB system can be achieved by pattern modification only of double single-ended system schematics/layouts, which are now available in the ASIC libraries of many companies.","PeriodicalId":111737,"journal":{"name":"Proceedings of CICC 97 - Custom Integrated Circuits Conference","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128304194","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 paper describes a data-recovery system which allows a 25% tolerance on the absolute position of the edge. The intelligent sample selector with memory-function retrieves the correct data from the multisampled input, even under the circumstances of wander, clock- and data-jitter and propagation phase-shift. The used approach does not require a PLL nor a DLL, since the straightforward mechanism results in the capture of the transmitted data with only the use of the central clock of the DSP. The retiming is done already at the first level-change and further at each following level-change. The good results are proven with measurements on a realisation with standard cells in a standard 0.7 /spl mu/m CMOS technology.","PeriodicalId":111737,"journal":{"name":"Proceedings of CICC 97 - Custom Integrated Circuits Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128527155","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}

We identified of 3D multilevel interconnect structures. We identified a reliable parasitic distributed RLC extraction method with the bounded local path 3D numerical simulation by using field solver. With the accurate RLC parasitic interconnect network and input driver for traversal clock delay evaluation, we investigated the impacts of variations in input slew, power supply voltage (V/sub cc/), and driver and load gate sizing on clock delay within the slow ramp region of driver gate as well as in the parasitic interconnect network. Input slew was found to be a dominant factor affecting clock delay sensitivity. This suggests that careful sizing of clock drivers, interconnects, and gate loads is required for minimal traversal clock delay. In addition, we used indirect on-chip electron beam probing to confirm that the simulated clock delays were in reasonable agreement with the measured delays.","PeriodicalId":111737,"journal":{"name":"Proceedings of CICC 97 - Custom Integrated Circuits Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124558440","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 signal generation and analysis circuits are entirely digital except for an extra charge-pump. They hence do not require calibration. Contrary to other phase-locked loop digital measurement schemes, a clock frequency larger than the phase-locked loop operating frequency is not necessary. Because the area overhead is small, our scheme is highly amenable to on-chip tuning of analog components for compliance to specifications. This method could also be used to implement built-in self-test for phase-locked loops. Experiments with discrete components show the jitter transfer function measuring method is sound.","PeriodicalId":111737,"journal":{"name":"Proceedings of CICC 97 - Custom Integrated Circuits Conference","volume":"254 15","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113988975","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}
