  1. 1. Distortion Cancellation in Time Interleaved ADCs

    University essay from Linköpings universitet/Elektroniska Kretsar och System

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

    Abstract : 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. READ MORE

  3. 2. Built-in self-test of analog-to-digital converters in FPGAs

    University essay from Linköpings universitet/Elektroniksystem

    Author : Petter Nilsson; [2014]
    Keywords : 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;

    Abstract : 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.

  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. Implementation of a Low-Cost Analog-to-Digital Converter for Audio Applications Using an FPGA

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Johan Hellman; [2013]
    Keywords : ADC; Sigma-Delta; FPGA; LVDS;

    Abstract : The aim of this master’s thesis is to implement an ADC (Analog-to-Digital Converter) foraudio applications using external components together with an FPGA (Field-ProgrammableGate Array). The focus is on making the ADC low-cost and it is desirable to achieve 16-bitresolution at 48 KS/s. READ MORE

  6. 5. High-Speed Hybrid Current mode Sigma-Delta Modulator

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Balakumaar Baskaran; Hari Shankar Elumalai; [2012]
    Keywords : Current mode Sigma Delta Modulator; Leslie-Singh Architecture; Switched Current Integrator; Folded Cascode Integrator; Current mode Flash ADC; High Speed Latched Comparator; Cascode Current Mirrors;

    Abstract : The majority of signals, that need to be processed, are analog, which are continuous and can take an infinite number of values at any time instant. Precision of the analog signals are limited due to influence of distortion which leads to the use of digital signals for better performance and cost. READ MORE
