Sammanfattning : .... LÄS MER
2. Low Phase Noise GaN HEMT Oscillator Design based on High-Q resonators
Sammanfattning : The thesis considers the design and optimization of oscillators targeting low phase noise, given boundary conditions from the technology. Crucial technology figures are power capability, RF noise figure, low-frequency noise and the quality factor (Q-factor) of the resonator. LÄS MER
3. Optimum GaN HEMT Oscillator Design Targeting Low Phase Noise
Sammanfattning : The thesis considers design of low phase noise oscillators, given the boundary condition of the used technology. Important conditions are the power handling of the active device, device noise floor, the quality factor of the resonator, bias settings, and low frequency noise. LÄS MER
4. 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
5. Fast dynamics and measurements of single-charge devices
Sammanfattning : In this thesis we present measurements on several different devices, including the single-Cooper-pair box (SCB), the single-electron box, tunable superconducting resonators and so called transmon qubits.By exploiting the quantum capacitance of the SCB, its state was measured by embedding the box in a radio-frequency resonator.
