The amplifier uses an interstage matching to increase the gain and to provide a better power match between the common-source and the common-gate transistor of the cascode device. Both the common-source and the common-gate transistor make use of an optimized round-table layout, which minimizes all terminal resistances and thus improves the mm-wave performance of the nMOS transistors. A record fmax of 300 GHz is achieved for a 40 mum round-table nMOS in 90 nm CMOS. The cascode amplifier achieves a gain of 7.5 dB at 60 GHz with a DC power consumption of only 6.7 mW. When compared to a shared-junction cascode amplifier or a two-stage common-source cascade amplifier, the presented cascode amplifier is favorable in terms of power gain and DC power consumption","PeriodicalId":436391,"journal":{"name":"2007 European Microwave Integrated Circuit Conference","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128751875","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}

An adequate efficient 3D-modeling of an A380 and subsequent scattering analysis and numerical system simulations are discussed for different model approximations. The modeling ranges from simple rectangular plates up to the most accurate 3D-model which includes the 3D voluminous tailfin. It has been shown that the simple models for the A380 fail for the grazing angle incidence even if the best available numerical methods are used. These models do not describe the physical features of the aircraft or the tail fin correctly. By that the modeling and the applied numerical methods is a critical issue in approximate models for complex objects in the possible and relevant geometrical scenarios.","PeriodicalId":436391,"journal":{"name":"2007 European Microwave Integrated Circuit Conference","volume":"210 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131932984","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}

In 4 V, the tunability of the IDCs was analyzed in terms of the electrode width and spacing by measuring reflection coefficients at 1 GHz.

This is a power reduction of 92.5 % for the Tx and 97.4 % for the Rx. Despite the low power consumption exhibited by the Tx an effective output power of -11 dBm is achieved. This is due to the fact that the Tx oscillator is turned on for a very short period of time compared to the bit period. The output of the Rx is then lengthened digitally to reproduce the correct duty cycle. The duty cycled Rx achieves an output voltage of 1 mV for an input power of -50 dBm. Also presented is a high impedance receiver which produces an output of 5 mV for an input power of -90 dBm.","PeriodicalId":436391,"journal":{"name":"2007 European Microwave Integrated Circuit Conference","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126195914","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}
