1. Designing and Evaluating a Delta-Sigma DAC for Hi-Fi Audio : To be used in an FPGA implementation
Master-uppsats, Linköpings universitet/DatorteknikSammanfattning : This thesis describes the design of a digital-to-analog converter using a DeltaSigma modulator. The converter’s purpose is to be used for Hi-Fi audio. The thesis is limited to the digital domain of the converter, which is the digital interpolation filter and digital Delta-Sigma modulator.

2. 16 GS/s Continuous-Time ΣΔ Modulator in a 22 nm SOI Process : a Simulation and Feasibility Study
Master-uppsats, Linköpings universitet/Tekniska fakulteten; Linköpings universitet/Elektroniska Kretsar och SystemSammanfattning : With a reference specification model in terms of 8 GS/s Sigma Delta Modulator in a 28 nm CMOS process consuming 890 mW, the purpose with this thesis is to construct a similar and simpler model but with higher specification demands. In a 22 nm SOI process with an input signal bandwidth of 500 MHz sampled at 16 GS/s with a power consumption below 2 W, the objective is to design a Continuous-Time Sigma Delta Modulator with verified simulated functionality on a transistor level basis.

3. Techniques for High-Speed Digital Delta-Sigma Modulators
Master-uppsats, Linköpings universitet/Institutionen för systemteknikSammanfattning : In this theses techniques for high-speed digital delta-sigma modulator(DDSM) structures are considered. Four techniques are applied andevaluated: unfolding, increasing the number of delay elements in theinner loop, pipelining/retiming, and optimizations provided by thesynthesis tool. Of interest is to see the speed-area-power trade-offs. LÄS MER
4. Micro-Power Inverter-Based Continuous-Time Sigma-Delta Modulator for Biosensor Applications
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : Biosensor applications have made promising progress during the last decade, presenting potentials and challenges at the same time. Meanwhile, digital signal processing (DSP) has become even more powerful than before, due to Moore's Law. LÄS MER
5. Design and Simulation of Miscellaneous Blocks of an All-Digital PLL for the 60 GHz Band
Master-uppsats, Elektroniksystem; Tekniska högskolanSammanfattning : A phase-locked loop commonly known as PLL is widely used in communication systems. A PLL is used in radio, telecommunications, modulation and demodulation. It can be used for clock generation, clock recovery from data signals, clock distribution and as a frequency synthesizer. Most electronic circuits encounter the problem of the clock skew. LÄS MER
