21. 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
22. Processing and characterization of GaN/SiC heterojunctions and SiC bipolar transistors
Sammanfattning : Silicon Carbide (SiC) and Gallium Nitride (GaN) are bothwide bandgap semiconductors that have been suggested for highpower, high voltage, and high temperature applications. Themost investigated SiC devices so far are the Schottky diode,PiN diode and the field effect transistor. LÄS MER
23. The Radio Frequency Single-Electron Transistor: Noise Properties and its Potential for Detecting Electrons on Helium
Sammanfattning : In this thesis the noise in the single electron transistor (SET) has been investigated.The charge sensitivity for the radio frequency single electron transistor(RF-SET) was measured. The demonstrated result is better than the previouslybest reported value both at 40 mK, and at 4.2 K. LÄS MER
24. GaAs based Vertical-Cavity Surface-Emitting Transistor-Lasers
Sammanfattning : The ever-increasing demand for broadband capacity of the global optical communication networks puts enormous requirements on the semiconductor laser used in the optical transmitter. Industrial standard bodies for optical communication project requirements of single-channel data rates as high as 100 Gbit/s around year 2020. LÄS MER
25. Direct Extraction of MOS Transistor Current Model Parameters
Sammanfattning : This thesis presents a study of MOS transistor model parameter extraction. The objective of this study was to develop an efficient, accurate, robust extraction strategy which determines physically reasonable parameter values. The direct parameter extraction approach was chosen to meet these requirements. LÄS MER
