However a bandpass DSM is commonly employed and is required to have a sampling frequency approximately four times the carrier frequency. At RF or microwave frequencies proprietary hardware was previously needed to implement the DSM. However, it is shown here in simulation and from experimental measurement that a suitable DSM for class S power amplifiers can be implemented at RF and microwave frequencies using mid-range FPGA technology.","PeriodicalId":205987,"journal":{"name":"2008 Workshop on Integrated Nonlinear Microwave and Millimetre-Wave Circuits","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122200897","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 startup of the different oscillation modes that coexist for the same values of the circuit components and parameters is also investigated. Phase noise and stability analysis have also been carried out to evaluate the performance of the circuit.

We show that the usual interpretation of current collapse as a bifurcation phenomenon for layouts with more than two fingers strictly holds only if inter-finger thermal coupling is neglected. Thus, predictive criteria based on the identification of singularity points associated to the nonlinear system may result inaccurate, or even fail, for the analysis of practical devices. On the other hand, numerical results show that a predictive analysis associated to the behavior of the FMs may still be provided. Finally, the proposed approach is applied to the stability analysis of different designs exploiting emitter ballasting or thermal shunt stabilization.","PeriodicalId":205987,"journal":{"name":"2008 Workshop on Integrated Nonlinear Microwave and Millimetre-Wave Circuits","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133012843","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}
