• Design of a time-based sigma-delta modulator 

    Dutta, Arnab Kumar, 1984- (2010-12-20)
    In this thesis, a time-based oversampling sigma-delta analog-to-digital converter (ADC) architecture is introduced. This system uses time, instead of voltage, as the analog variable for it quantizer, where the noise shaping ...
  • IC design for reliability 

    Zhang, Bin (2009-10-23)
    As the feature size of integrated circuits goes down to the nanometer scale, transient and permanent reliability issues are becoming a significant concern for circuit designers. Traditionally, the reliability issues were ...
