The noise model is based on the classical impedance-field method, implemented within the framework of a frequency-domain numerical drift-diffusion physical model. The paper is mainly devoted to the experimental validation of the noise model, which is performed for a re& tic caw study (a 0.6 jtm GEGMarconi MESFET). Stress is laid on the role played by the high-field diffusivity model in noise analysis, which allows a good match to be achieved between measurements and simulation for both the noise figure and the op timuni source impedance.","PeriodicalId":234490,"journal":{"name":"AMPC Asia-Pacific Microwave Conference,","volume":"235 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115752304","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}
