1. Nonlinear Modeling of FETs for Microwave Switches and Amplifiers
Sammanfattning : The exponential growth in wireless systems require rapid prototyping of radio frequency circuits (RF) using computer-aided design (CAD) enabled models. Most of the RF circuits (e.g. switches, amplifiers, mixers, etc. LÄS MER
2. Stochastic model updating and model selection with application to structural dynamics
Sammanfattning : Uncertainty induced by our incomplete state of knowledge about engineering systems and their surrounding environment give rise to challenging problems in the process of building predictive models for the system behavior. One such challenge is the model selection problem, which arises due to the existence of invariably multiple candidate models with different mathematical forms to represent the system behavior, and so there is a need to assess their plausibility based on experimental data.

3. FET mixers and nonlinear FET models for intermodulation analysis
Sammanfattning : .... LÄS MER
4. Case studies in omniparametric simulation
Sammanfattning : In the eld of particle systems and growths models simulation is an important tool. When explicit calculations are too complex or impossible to perform we may use simulations instead. We adapt a new technique here denoted omniparametric simulation, to the two-type Richardson, Ising and Potts models. LÄS MER
5. Symmetrical FET Modeling
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
