16. Monolithic Integrated Oscillators - Phase Noise Analysis and Inductor Modeling
Sammanfattning : This doctoral dissertation studies voltage controlled oscillators (VCOs) that operate at low supply voltages. Due to smaller transistor sizes and lower supply voltage ratings with every new CMOS technology, voltage headroom is diminishing. LÄS MER
17. MMIC-based Low Phase Noise Millimetre-wave Signal Source Design
Sammanfattning : Wireless technology for future communication systems has been continuously evolving to meet society’s increasing demand on network capacity. The millimetre-wave frequency band has a large amount of bandwidth available, which is a key factor in enabling the capability of carrying higher data rates. LÄS MER
18. Phase Noise Tolerant Modulation Formats and DSP Algorithms for Coherent Optical Systems
Sammanfattning : Coherent detection together with multilevel modulation formats has the potential to significantly increase the capacity of existing optical communication systems at no extra cost in signal bandwidth. However, these modulation formats are more susceptible to the impact of different noise sources and distortions as the distance between its constellation points in the complex plane reduces with the modulation index.

19. Detection in Digital Communication Systems with Phase Noise
Sammanfattning : In every communication system, the limitations of the hardware sets a constraint on the overall system performance. More often than not, these limitations are not taken into account during the system design stage where the hardware is considered ideal. LÄS MER
20. Digital Phase Locked Loops for Radio Frequency Synthesis
Sammanfattning : The demands for an ever higher data rate and a more varied functionality at minimal cost and power consumption have been the driving force behind most innovations in wireless communication systems. Intensive efforts have been made to develop Radio Frequency (RF) Integrated Circuits (ICs) and systems using low-cost Complementary Metal Oxide Semiconductor (CMOS) processes. LÄS MER
