Through direct measurement of current transients of both source and drain terminals, a characterisation technique has been developed to: (i) analyse the transient current degradations from μS to seconds, and (ii) evaluate the drain and gate induced charge trapping mechanisms. Two degradation mechanisms of current are observed: bulk trapping at a short time <1ms); and surface trapping and redistribution (>lms). The bulk charge trapping is found to occur during both ON and OFF states of the device when Vns>0V; where its trapping time constant is independent of bias conditions. In addition, the time constant of the slower current degradation is found to be mainly dependent on surface trapping and redistribution, not by the second heat transient.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121780691","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 the output frequency of the tripler is set to be 90 GHz with a 10% bandwidth. The simulation shows a conversion loss of 13-13.8 dB in the pass-band with an input power of 13–20 dBm.

Several key RF performance parameters of the LNA with different substrate thickness are evaluated through full-wave electromagnetic (EM) simulations. The proposed LNA operating at 5.5 GHz is fabricated in a cost-effective 0.25 μm SiGe BiCMOS technology (IHP process SGB25V; ft = 75 GHz). The Si chip is thinned to ~38 μm in order to be embedded seamlessly into a flexible foil system. The small-signal gain of the LNA, measured on the chuck is 14.32 dB before thinning. The measured center frequency on the thin silicon (thickness of 38 μm) is shifted about 700 MHz towards higher frequencies compared to the thick silicon due to the image mirror currents within the conducting material at the backside of the chip. The measured noise figure (NF) with the thick and thin substrate on the conducting material is around 3.36 dB at 5.5 GHz and 3.74 dB at 6.3 GHz., respectively.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122991098","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 study was performed by characterization of bias voltage and temperature dependence between −25°C to 75°C of a GaN MMIC LNA. The performance, in terms of gain, linearity and noise, degraded, at elevated chip temperatures. Nonlinear behavioral models were developed and used to predict performance for different bias and temperature conditions. Bias conditions to achieve constant gain and noise figure versus temperature are determined. Enhanced RF performance, with improved gain and linearity is demonstrated and is shown to require increased power and involves a trade-off between improving noise figure and gain.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127305477","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}
