  1. 16. CMOS Analog-to-Digital Converters - Analysis, Modeling, and Design

    Författare :Martin Andersson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A high-performance and flexible analog-to-digital converter (ADC), that can be integrated in deep-submicron CMOS technology, is a key building block for reduced size, cost and power consumption of digital communication systems. This dissertation concerns the investigation of particular problems associated with the design of such ADCs. LÄS MER

  3. 17. On Design of a Compact Primary Switched Conversion System for Electric Railway Propulsion

  5. 19. Modulation and channel effects in digital communication

    Författare :Sara Sandberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : This thesis investigates three possible methods to increase the performance of digital communication systems, with focus on wireless systems, by accounting for some of the channel effects that may occur. The modulation scheme plays an important role in the impact of different channel effects on system performance and this work considers both a single-carrier system and orthogonal frequency-division multiplexing (OFDM).

  7. 20. Interfacing Complementary Separation Techniques with Mass Spectrometry Utilizing Electrophoresis, Nanoparticles, and Functionalized Magnetic Beads

    Författare :David Malmström; Jonas Bergquist; Magnus Wetterhall; Alejandro Cifuentes; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Capillary electrophoresis (CE) has during the last two decades become more robust and been able to separate neutral analytes without compromising the downstream detection. An interesting aspect in CE compared to more commonly used high-performance liquid chromatography is the orthogonal separation mechanism provided by CE. LÄS MER
