  1. 1. CMOS Parallel-Sampling Receivers

    Författare :Henrik Johansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : As the processing capacity of the microelectronic circuits increases, the demands on the interconnects will also increase. Hence, there is a need for higher bandwidth to the chips. This dissertation discusses the possibilities to improve the input data rate to CMOS integrated circuits, which is the most common integrated circuit technology today. LÄS MER

    Sammanfattning : Interdisciplinary research between medicine and microsystem engineering creates new possibilities to improve the quality of life of patients or to further enhance the performance of already existing devices. In particular, microsystems show great potential for the realization of biosensors and sampling devices to monitor bioanalytes with minimal patient discomfort. LÄS MER

  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

  5. 4. Optimisation of Railway Switches and Crossings

    Författare :Björn Pålsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel and rail wear; railway turnout; optimisation; switch crossing; dynamic vehicle-turnout interaction;

    Sammanfattning : Methods for simulation-based optimisation of the design of railway turnouts (switches & crossings, S&C) are developed and demonstrated. Building on knowledge of dynamic wheel–rail interaction in turnouts, it is investigated how rail profile degradation can be reduced by the optimisation of geometry and component stiffness of the track superstructure.

  7. 5. On PLL Modeling and Design in Nanometer‐Scale CMOS

    Författare :Anders Jakobsson; Shaofang Gong; Adriana Serban; Hannu Tenhunen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-locked loop; Frequency synthesizer; Calibration; Modelling; Quantized-state system; Phase interpolator; Sub-sampling PLL;

    Sammanfattning : Integrated circuits play a vital role in our everyday lives, from wireless gadgets and multimedia players to sensors and processors that control vital infrastructure. Since most electronic circuits need a clean, stable clock or carrier to function, one of the most important components of integrated circuits is the phase-locked loop. LÄS MER
