  • An automatic architecture generator for sigma-delta modulators considering component non-idealities 
    Yetik, Ömer. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    In this thesis, a tool generated in MATLAB environment for automatic modeling and architecture synthesis of sigma-delta modulators is introduced. The tool is capable of generating the parametric signal and noise transfer ...
  • Current mode continuous time sigma delta converter design 
    Yapar, Ufuk. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    Most sigma delta modulators are realized in the discrete-time domain using circuit techniques such as switched capacitor. In typical discrete time implementations, there are some speed constraints. For example, maximum ...
  • Digital filter design, error modeling and error correction in sigma-delta modulators 
    Genç, Necmiye. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    Modern electronic systems that are used in computers, automotive, communication, etc., are mostly mixed-signal systems. To implement mixed-signal systems, it is necessary to convert analog signals into the digital domain ...
  • High performance adaptive sigma delta modulator designs 
    Kurşunoğlu, Sedef. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    Improvements in VLSI technology enabled data converters with increased speed. When compared to conventional converters, sigma delta modulators have a higher sampling speed for resolution; and they are less sensitive to ...
  • High performance adaptive sigma delta modulator designs 
    Gökdel, Yiğit Dağhan. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    In this work two different solutions to the saturation problem of the integrator building block of Sigma Delta modulators are presented. Saturation causes an error that limits the dynamic input range of the Sigma Delta A/D ...
  • Implementation and performance evaluation of sigma-delta modulators 
    Sağlamdemir, Muharrem Orkun. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    SigmaDelta A/D converters have recently become popular since they achieve high resolution by means of oversampling without the need of high accuracy matching of elements and complex analog circuitry. They even reach higher ...
  • Low power consumption continuous time sigma-delta modulator design 
    Çeliker, Hikmet. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2016., 2016.)
    Mobile electronic devices have important roles in our daily lives. While they are getting smaller, their functionality is increasing. As the charge capacity of the batteries is limited, it should be spent e ciently. Low ...
  • Power optimization and modeling of switched-capacitor integrators suitable for delta-sigma modulators 
    Evci, Gökhan. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2010., 2010.)
    In this thesis, the power dissipation aspects of the Switched-Capacitor (SC) integrators used in Delta-Sigma ( ) modulators are treated. Delta-Sigma modulators which employ oversampling are one of the most critical types ...
  • Second order sigma delta modulator architecture with low voltage swing at the output of the first integrator 
    Çakır, Necmettin Levent. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2010., 2010.)
    The technological improvements in digital Very Large Scale Integration (VLSI) circuits increase the need of analog digital converter with high performance and lower power consumption. Primarily, the oversampling techniques ...
