However accurate predictions of circuit performances can be obtained only if non-linear CAD tools are available. A new method has been proposed allowing to overcome the difficulties encountered with commercial CAD software packages when we want to simulate synchronized circuits. For the first time a 60/30 GHz MMIC analog frequency divider has been designed and processed with a 0.25/spl mu/m HEMT process at the THOMSON-CSF foundry. The results obtained are very close to the predicted performances and allow us to think that broadband analog frequency dividers may now be designed at higher frequencies.","PeriodicalId":328819,"journal":{"name":"Proceedings of 1994 IEEE GaAs IC Symposium","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127944113","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}

Meeting cost and performance goals requires careful attention to system level design and partitioning such that appropriate technologies are employed in cost-effective solutions. New circuit designs and techniques are required to meet size, power, and regulatory restrictions. This provides an exciting opportunity for GaAs, silicon and other technologies. This paper will present several system level architectures for present and proposed radio-based communication systems.

We have found that a hydrogen partial pressure in the order of 2 torr will cause Ids change by 20% in about 800 hours at 125/spl deg/C and about 300 hours at 150/spl deg/C. The signature of hydrogen degradation is a sudden and significant drain current degradation followed by some recovery. It appeared that the degradation is both temperature and H/sub 2/ partial pressure dependent. Failure analysis indicates that the degradation is localized under the gate and that the major failure mechanism is due to the effective gate voltage being modified negatively by the atomic hydrogen.","PeriodicalId":328819,"journal":{"name":"Proceedings of 1994 IEEE GaAs IC Symposium","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126678597","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}
