The novel technique is based on a Green's function approach, where the response of the device to lattice (ambient) temperature variations is recovered by means of the linearization of the device equations around the nominal device working point and temperature. The same Green's Functions are also used for other device variability analyses, e.g. random doping fluctuations or geometrical variations. A linear superposition of the device response to temperature variations with any other parameter variation, allows for a temperature-dependent device variability analysis, with virtually the same numerical burden as the fixed temperature one. In this paper we verify the technique against non-linearized (MonteCarlo) analyses. A metal gate FinFET is considered in two case studies: temperature-dependent deterministic variations of the fin doping concentration; temperature-dependent random workfunction variations due to metal granularity. The approach is extremely accurate up to 80 K above ambient temperature with a huge reduction in simulation time with respect to MonteCarlo approach.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"146 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":"131706900","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}

To this aim, an analog DPA is designed and characterized. The equivalent digital version, which only differs by the absence of the input power divider, is also realized and analyzed. This ensures a fair comparison of the two topologies. Power-dependent input signal splitting between the main and auxiliary branches as well as adaptive phase alignment are adopted in the digital version to compensate for the back-off efficiency degradation as well as other shortcomings typically shown by traditional analog DPAs. For the first time, the performance figures of merit of the equivalent analog and digital DPAs are compared one-to-one systematically. The comparison over the 3.1-3.7 GHz range shows a superior efficiency performance of the digital DPA over the analog one, both at saturation and in back-off. Furthermore, the dual-input control also ensures higher gain and saturated output power.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"22 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":"125398663","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}

There is increasing evidence that soil organisms significantly contribute to shaping the biodiversity and functioning of plants in terrestrial ecosystems, as well as the ecological and evolutionary responses to environmental change. While still limited, knowledge about the spatial and temporal patterns of soil biodiversity and mechanistic understanding of how it regulates the structure and function of terrestrial ecosystems are growing rapidly. In this session we will be exploring a number of questions: How to integrate this new understanding into existing and novel frameworks of biodiversityfunctioning research?, How to best improve our understanding of the mechanisms that shape complex soil biological communities at different spatial and temporal scales?, How to best study the impact of soil biodiversity on plant traits in response to environmental change?, How do we most effectively integrate insights of soil biodiversity research into sustainable land management decisions?. The presentations in this workshop may include a range of approaches, methodologies and tools. These may include spatial analysis, aboveground and belowground biodiversity monitoring, functional traits and ecosystem services, decisionsupport systems, capacity development of stakeholders, local knowledge on biodiversity interactions and land management.

Our approach involves inverse and forward surrogate modeling techniques. The inverse model is utilized to obtain a good initial transformer dimensions at the equivalent network modeling level. The forward surrogates (here, space mapping ones) permit rapid design closure at the full-wave EM simulation modeling level. The proposed methodology is demonstrated using a four-section compact transformer for energy harvesting applications. The circuit dimensions are scaled within wide ranges of the load impedance magnitude and phase (from 30 to 130 ohm and −26.5 to 26.5 degrees, respectively) at low computational cost corresponding to up to three EM analyses of the transformer structure. Reliability of the framework is validated through comprehensive numerical experiments as well as application case studies. The latter are provided to indicate that appropriate transformer design is critical for performance improvement of the rectifier circuits, both in terms of operational bandwidth and matching.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"14 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":"133113874","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}
