1. Microwave Transistor Noise Model Extraction Methods and a Non-Contacting Scattering Parameter Measurement Method
Sammanfattning : This thesis has two parts. The first part discuss noise model extraction methods for FETs. The second part describe theory and implementation of a non-contacting S-parameter measurement method. Noise is an important aspect for a circuit designer, because noise generated in the circuit is a sensitivity limiting factor. LÄS MER
Sammanfattning : This thesis deals with the modelling of THz planar Schottky diodes, focusing on analyses of the geometry- dependent parasitics and the diode chip thermal management. Moving towards higher operating frequencies, the electromagnetic couplings pose significant limitations on the diode performance. 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
Sammanfattning : Time Domain Reflectometry (TDR) has been used for localization of transmission line discontinuities in diverse applications. Various challenges have to be addressed when applying TDR for localization of insulation degradation in power cables. LÄS MER
