  1. 1. Symmetrical FET Modeling

    Författare :Ankur Prasad; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; switch model; symmetrical model; nonlinear model; small-signal model; GaAs; Microwave FET; GaN;

    Sammanfattning : This thesis deals with empirical modeling of symmetrical Field-Effect Transistors (FETs). It covers three distinct topics within the areas of modeling and parameter extraction of microwave FETs.First, the symmetry of FET devices is addressed. Such devices are often used in transceivers as a building block for switches. LÄS MER

    Sammanfattning : This thesis deals with three distinct topics within the areas of modeling, analysis and circuit design with microwave field effect transistors (FETs). First, the extraction of FET small-signal model parameters is addressed. LÄS MER

  5. 4. Corporate Social Responsibility practice in the mining industry

    Författare :Helena Ranängen; Annik Magerholm Fet; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental Management; Miljöledning;

    Sammanfattning : Corporate Social Responsibility (CSR) has frequently been discussed throughout the years. However, in the 1990s criticism of multinational companies and their production in developing countries resulted in new and more demanding requirements from society. LÄS MER

  7. 5. Resitive FET Mixers

    Författare :Klas Yhland; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis presents theory, device models and circuits related to resistive FET mixers: A wave analysis for resistive mixers The analysis gives an intuitive estimate of resistive mixer performance when most parameters are unknown. It is based on the assumption that all mixing terms generated in the mixer are terminated with the same impedance. LÄS MER
