    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MODFET; soft-breakdown; cold FET; large-signal; source balance; SDHT; dispersion; noise figure; temperature noise model; small-signal; TEGFET; direct extraction; Chalmers model; noise parameters; modeling; HEMT; HFET; noise;

    Abstract : Transistor models are very important in the design of Monolithic Microwave Integrated Circuits (MMICs). Circuit simulations based on accurate transistor models are one of the keys to high circuit yield. Transistor models can also be used to trace problems in the device fabrication processes. READ MORE

    Abstract : Salmonella enterica serovar Typhimurium (S.Tm) causes enterocolitis with significant worldwide morbidity and mortality. The general aim of this thesis is to investigate variation in host cell invasion mechanisms used by S.Tm across different host cell contexts, as well as the influence of bacterial cell-cell heterogeneity on invasion-relevant S.
