  1. 1. Integrated Antennas Monolithic and Hybrid Approaches

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Erik Öjefors; Anders Rydberg; Sayan Mukherjee; Duixian Liu; [2006]
    Nyckelord :Electronics; antenna travelling wave arrays; antenna phased arrays; phase shifters; micromachining; silicon; monolithic microwave integrated circuits; dipole antennas; loop antennas; slot antennas; Elektronik;

    Sammanfattning : This thesis considers integration of antennas and active electronics manufactured on the same substrate. The main topic is on-chip antennas for commercial silicon processes, but hybrid integration using printed circuit board technology is also addressed. LÄS MER

  2. 2. Monolithic Integrated Oscillators - Phase Noise Analysis and Inductor Modeling

    Detta är en avhandling från Department of Electroscience, Lund University

    Författare :Niklas Troedsson; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monolithic inductor; Monolithic integrated oscillator; CMOS; Bluetooth; low voltage; voltage controlled oscillator; Elektronik och elektroteknik; Electronics and Electrical technology; inductor modeling; phase noise analysis; quadrature voltage controlled oscillator;

    Sammanfattning : This doctoral dissertation studies voltage controlled oscillators (VCOs) that operate at low supply voltages. Due to smaller transistor sizes and lower supply voltage ratings with every new CMOS technology, voltage headroom is diminishing. LÄS MER

  3. 3. Monolithic and semi-monolithic translucent zirconium-dioxide restorations aspects on design, material and strength

    Detta är en avhandling från Malmö university, Faculty of Odontology

    Författare :Fahad Bakitian; [2020]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Although many clinical reports have shown high rates of clinical success associated with fixed dental restorations made of traditional zirconium-dioxide (zirconia), clinical failure due to improper design aiming to achieve high strength and optimal aesthetics, still occurs. Previous clinical and laboratory studies indicated that veneering porcelain and the connector represent the weak parts of the fully-veneered zirconia restorations where failure may occur. LÄS MER

  4. 4. Mechanical and Microstructural Properties of Monolithic Zirconia

    Detta är en avhandling från Malmö university, Faculty of Odontology

    Författare :Keisuke Nakamura; Göteborgs universitet.; Gothenburg University.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; zirconia; flexural strength; microstructure; fracture resistance; monolithic crown; low-temperature degradation; phase transformation;

    Sammanfattning : Zirconia has been widely used in dentistry to improve the strength of ceramic restorations maintaining aesthetics. In addition, zirconia is increasingly being used for monolithic crowns without veneering porcelain. LÄS MER
