The effective delivery of such electrical power must also allow for efficient removal of the heat generated by the electronics circuits. By exploiting appropriate MCM technology, these thermal concerns are satisfied while eliminating to a maximum extent conventional circuit packaging parasitics which limit performance of high frequency systems. The overlay interconnect MCM approach used by GE/TI places IC chips first, into a structure for the most advantageous thermal management, while eliminating conventional packaging resistance, inductance and capacitance effects. Several designs constructed with overlay interconnect demonstrate the highest frequency operation and thermal performance of MCMs to date. System designs with 400 MHz and greater clock operation and dissipating 50 W are described.<<ETX>>","PeriodicalId":143140,"journal":{"name":"Proceedings 1993 IEEE Multi-Chip Module Conference MCMC-93","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133083976","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}

Here, an approach for generating, with an accuracy check, all the dominant poles within the frequency range of interest using complex frequency hopping (CFH) is presented. The method, based on a binary search strategy, uses multiport complex moment-matching in the frequency s plane. CFH allows for the efficient analysis of large networks which include lossy, coupled transmission lines and nonlinear terminations, with estimated waveforms converging to simulation accuracy. Several examples which demonstrate the accuracy of the proposed technique are presented.<<ETX>>","PeriodicalId":143140,"journal":{"name":"Proceedings 1993 IEEE Multi-Chip Module Conference MCMC-93","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130107394","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}

Three VLSI chips of various sizes and I/O requirements have been synthesized based on a standard-cell library for both wire-bond and flip-chip.

The expression is used to model measured scattering parameter characteristics up to 18 GHz, for different line types. Excellent correspondence between measurements and simulations is achieved, even when magnetic effects of a thick nickel barrier layer are involved.
