1. Microwave power device characterization
Sammanfattning : The first part of the thesis covers work done on device characterizationmethods. A statistical method for estimating small-signal model parametersin FET-models was proposed. A maximum likelihood estimator wasderived and the new method was compared to a standard direct extractiontechnique. LÄS MER
2. Ferroelectric Thin Films on Si-substrate for Tunable Microwave Applications
Sammanfattning : The thesis presents the development of microwave tunable devices based onferroelectric thin films. The main tasks in this work are the fabrication, optimization, andintegration of ferroelectric thin film into Si-MMIC. LÄS MER
3. Microwave CMOS Beamforming Transmitters
Sammanfattning : The increase of the consumer electronics market the last couple of decades has been one of the main drivers of IC process technology development. The majority of the ICs are used in digital applications, and for these CMOS is the choice of technology. The urge to squeeze more transistors on to a given area has led to shrinking feature sizes.

4. Microwave Breakdown: Physics and Applications
Sammanfattning : Theories for microwave breakdown in gases, with emphasis on Air, are presented in this thesis. Underlying physical processes are described together with models suitable for scientific research and technical development. LÄS MER
5. Microwave measurement techniques for industrial process monitoring and quality control
Sammanfattning : Process monitoring and quality control by sensor measurements are essential for the automatisation and optimisation of many industrial manufacturing processes. This thesis is concerned with microwave sensing, which is a measurement modality with potential to improve the in-line sensing capabilities in several industries. LÄS MER
