  1. 1. Design and Implementation of Sigma-Delta Converter : in Oversampling frequency

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Yaobin Pan; Xizhuo Li; [2016]
    Nyckelord :Sigma-Delta converters; Oversampling; Analog-Digital converters;

    Sammanfattning : Nowadays, Sigma-Delta analog-to-digital converters have been widely used in the technology of analog-to-digital conversion. It depends on the merits that the approach of Sigma-Delta has. The signal converted by oversampling is precise and well-suited in signal processing systems. LÄS MER

  3. 2. Distortion Cancellation in Time Interleaved ADCs

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Naga Thejus Sambasivan Mruthyunjaya; [2015]
    Nyckelord :Time-Interleaved ADC; Post correction; Blind calibration; Harmonics cancellation; Mismatch analysis; Linearisation;

    Sammanfattning : Time-Interleaved Analog to Digital Converters (TI ADC) consist of several individual sub-converters operating at a lower sampling rate, working in parallel, and in a circular loop. Thereby, they are increasing the sampling rate without compromising on the resolution during conversion, at high sampling rates. LÄS MER

  4. 3. 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.

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

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

    Författare :Jiazuo Chi; [2014]
    Nyckelord :;

    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

  7. 5. Design of an all-digital, reconfigurable sigma-deltamodulator

    Master-uppsats, Elektroniksystem; Tekniska högskolan

    Författare :Syed Asmat Ali Shah; Sohaib Ayaz Qazi; [2012]
    Nyckelord :;

    Sammanfattning : This thesis presents a model of reconfigurable sigma-delta modulator. These modulators areintended for high speed digital Digital to Analog Converters. The modulators are intendedto reduce complexity of current steering DACs and also considered as a front end of dataconverters. LÄS MER
