  1. 1. Designing and Evaluating a Delta-Sigma DAC for Hi-Fi Audio : To be used in an FPGA implementation

    University essay from Linköpings universitet/Datorteknik

    Author : Gustav Malmström; [2023]
    Keywords : Delta-Sigma; DAC;

    Abstract : 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. READ MORE

  3. 2. Techniques for High-Speed Digital Delta-Sigma Modulators

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Hsu Ching; [2016]
    Keywords : ASIC; Unfold; Pipeline; Higher Order; digital delta sigma modulator;

    Abstract : 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. READ MORE

  4. 3. Micro-Power Inverter-Based Continuous-Time Sigma-Delta Modulator for Biosensor Applications

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Jiazuo Chi; [2014]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 4. Design and Simulation of Miscellaneous Blocks of an All-Digital PLL for the 60 GHz Band

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Hadiyah Butt; Manjularani Padala; [2013]
    Keywords : ADPLL; PLL; DCO; TDC;

    Abstract : 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. READ MORE

  6. 5. Investigation of Mechanisms for Spur Generation in Fractional-N Frequency Synthesizers

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Sohail Imran Saeed; [2012]
    Keywords : DDSM; Digital Delta Sigma Modulator; EFM; Error Feedback Modulator; PLL Phase Locked Loop; Fractional N Frequency Synthesizer; Spur; Spurs;

    Abstract : With the advances in wireless communication technology over last two decades, the use of fractional-N frequency synthesizers has increased widely in modern wireless communication applications due to their high frequency resolution and fast settling time. The performance of a fractional-N frequency synthesizer is degraded due to the presence of unwanted spurious tones (spurs) in the output spectrum. READ MORE
