  1. 1. 16 GS/s Continuous-Time ΣΔ Modulator in a 22 nm SOI Process : a Simulation and Feasibility Study

    University essay from Linköpings universitet/Tekniska fakulteten; Linköpings universitet/Elektroniska Kretsar och System

    Author : Eric Öberg; Gustav Kindeskog; [2018]
    Keywords : sigma delta modulator;

    Abstract : 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. 2. Design and Implementation of Sigma-Delta Converter : in Oversampling frequency

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

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

    Abstract : 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. READ MORE

  4. 3. 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

  5. 4. Interferometer Design for Attosecond Experiments

    University essay from Lunds universitet/Fysiska institutionen

    Author : Simon Ek; [2015]
    Keywords : FRED; attophysics; atomic physics; stability; simulations; MATLAB; interferometer design; interferometers; error propagation; Physics and Astronomy;

    Abstract : Resolving fast events, such as electron dynamics, requires short light pulses. To this date the shortest available light pulses are created using High-order Harmonic Generation (HHG) and have a duration of a few hundred attoseconds (1 as = $10^{-18}$ s). READ MORE

  6. 5. 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.
