  4. 3. Modeling and Analysis of Wideband Sigma-Delta Noise Shapers

    Författare :Andreas Göthenberg; KTH; []
    Nyckelord :Data Converters; Oversampling; Sigma-Delta; Modulators; Wideband; Noise Shapers; Sampling Switches; Substrate Noise Coupling;

    Sammanfattning : The continuous evolution of CMOS technologies towards deepsubmicron processes has provided new opportunities forintegration of mixed-signal systems on single monolithicintegrated circuits. In order to find the optimal usage of CMOStechnology and robustness against undesired mixed-signalcouplings, new approaches to CMOS front-end integration areneeded. LÄS MER
