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

    Master-uppsats, Linköpings universitet/Datorteknik

    Författare :Gustav Malmström; [2023]
    Nyckelord :Delta-Sigma; DAC;

    Sammanfattning : 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. LÄS MER

  3. 2. Modelling and Analysis of Substrate Noise in Delta Sigma ADCs

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Abu Darda; [2017]
    Nyckelord :Analog Mixed Signal Design; Delta Sigma ADC; Substrate Noise; System Level Modelling; Behavioural Level Modelling; Analog blandad signaldesign; Delta Sigma ADC; Substrate Noise; Systemnivåmodellering; Behavioralnivåmodellering;

    Sammanfattning : The rapid development in the semiconductors industry has enabled the placement of multiple chips on a single die. This has helped boost the functionality of modernday application specific integrated circuits (ASICs). Thus, digital circuits are being increasingly placed along-side analog and RF circuits in what are known as mixed signal circuits. LÄS MER

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

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

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

    Sammanfattning : 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

  5. 4. Built-in self-test of analog-to-digital converters in FPGAs

    Master-uppsats, Linköpings universitet/Elektroniksystem

    Författare :Petter Nilsson; [2014]
    Nyckelord :FPGA; BIST; ADC; dynamic test; static test; linearity; DNL; INL; offset; gain error; FFT; SNR; THD; delta-sigma; sigma-delta; DAC; high-level synthesis; HLS; IEEE Standard 1241;

    Sammanfattning : When designing an ADC it is desirable to test its performance at two different points in the development process. The first is characterization and verification testing when a chip containing the ADC has been taped-out for the first time, and the second is production testing when the chip is manufactured in large scale.

  7. 5. Low Power Current Mode Delta-SigmaADC using Ring Oscillator basedQuantizer

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Ibrahim Kazi; [2013]
    Nyckelord :;

    Sammanfattning : Low power ADCs have wide range of applications, from battery operated systems like biomedical devices to on chip power measurement systems. A more digital implementation is also desirable to take advantage of the technology scaling in digital CMOS technologies. LÄS MER
