  2. 6. Experimentally Based HFET Modeling for Microwave and Millimeter Wave Applications

    Author : Mikael Garcia; Chalmers tekniska högskola; []
    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 : The HIV protease is an essential enzyme for HIV replication and constitutes an important target in the treatment of HIV/AIDS. Efficient combination therapies using inhibitors of the reverse transcriptase and protease enzymes have led many to reevaluate HIV infections from a terminal condition to a chronic-but-manageable disease in the developed world.
