  2. 2. Modeling and Analysis of Wideband Sigma-Delta Noise Shapers

    University dissertation from Kista : Mikroelektronik och informationsteknik

    Author : Andreas Göthenberg; KTH.; [2003]
    Keywords : Data Converters; Oversampling; Sigma-Delta; Modulators; Wideband; Noise Shapers; Sampling Switches; Substrate Noise Coupling;

    Abstract : 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. READ MORE

  5. 5. Wideband Sigma-Delta Modulators

    University dissertation from Stockholm : KTH

    Author : Xiaolong Yuan; KTH.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sigma-delta modulator; feedforward; reconfigurable; quadrature bandpass filtering; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektronik;

    Abstract : Sigma-delta modulators (SDM) have come up as an attractive candidatefor analog-to-digital conversion in single chip front ends thanks to the continuousimproving performance. The major disadvantage is the limited bandwidthdue to the need of oversampling. READ MORE
