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

    University dissertation from Department of Electroscience, Lund University

    Author : Niklas Troedsson; Lunds universitet.; Lund University.; [2005]
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 2. Impedance of Soft Magnetic Multilayers Application to GHz Thin Film Inductors

    University dissertation from Stockholm : Fysik

    Author : Andrey Gromov; KTH.; [2001]
    Keywords : inductor; impedance; magnetic; eddy currents; FMR;

    Abstract : A theoretical approach to calculating impedance of metallicmagnetic/conductor layered structures is developed. Thefrequency range considered extends to the ferromagneticresonance region of soft magnetic films (of the order of 1GHz). READ MORE

  3. 3. Development of SiC MESFET Based MMIC Technology

    University dissertation from Stockholm : Fysik

    Author : Mattias Sudow; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIM capacitor; high power amplifier; limiter; SiC MMIC; SiC MESFET; SiC Schottky; TFR; high level mixer; spiral inductor; via-hole;

    Abstract : A SiC MESFET based MMIC process has been successfully developed. This technology has its main potential in high power microwave circuits. It will offer the benefits of the high integration seen in GaAs MMIC at the same time as it will offer the benefits of the high voltage operation seen in Si LDMOS and Si BJTs. READ MORE

  4. 4. CMOS Transceiver Front-Ends in Mobile Communication Handsets - Architectures and Building Blocks

    University dissertation from Department of Electroscience, Lund University

    Author : Pieternella Cijvat; Ellie Cijvat; Lunds universitet.; Lund University.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RF CMOS; Wireless Communication; Receiver; Transmitter; Power Amplifier; Harmonic Distortion; Electrical engineering; Elektroteknik; Telecommunication engineering; Telekommunikationsteknik; Electrotechnology; Elektroteknik alt Electrical engineering;

    Abstract : For mobile communication systems in the low-GHz range, CMOS has increasingly become the technology of choice, and the level of integration in mobile handsets has risen. The use of off-chip components, which increases the handset assembly time and costs, is preferably avoided. READ MORE

  5. 5. DC-DC Converters - Dynamic Model Design and Experimental Verification

    University dissertation from Department of Industrial Electrical Engineering and Automation, Lund Institute of Technology

    Author : Bengt Johansson; Lunds universitet.; Lund University.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; buck; dc-dc converter; modeling; audio susceptibility; current-mode control; load current; gain scheduling; current transformer; experimental verification; Electronics and Electrical technology; Automation; Elektronik och elektroteknik; Elektroteknik; Electrical engineering; reglerteknik; robotteknik; Automatiska system; control engineering;

    Abstract : To obtain high performance control of a dc-dc converter, a good model of the converter is needed. The load usually affects the dynamics and one way to take this into consideration is to regard the load as a part of the converter. The load is often the most variable part of this system. READ MORE
