  1. 1. 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

  3. 2. 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

  4. 3. 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

  5. 4. 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

  6. 5. Measurement of dynamic parameters of Delta-Sigma ADC

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Yixiang Zhao; Hao Niu; [2012]
    Keywords : DSP; Delta-sigma converter; Dynamic parameters; Evaluation Module; Matlab.;

    Abstract : In present day, digital signal processing (DSP) is a popular technology and widely used in many fields. There have increasing number of applications that need high resolution converters. Therefore, analog-to-digital converters play a major role in DSP, and a well-performed ADC will enhance the performance of a certain system. READ MORE
