  2. 21. Cooling Strategies for Wave Power Conversion Systems

    Author : Antoine Baudoin; Cecilia Boström; Anne Blavette; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; power conversion system; thermal management; power elctronics; passive cooling; natural convection.;

    Abstract : The Division for Electricity of Uppsala University is developing a wave power concept. The energy of the ocean waves is harvested with wave energy converters, consisting of one buoy and one linear generator. The units are connected in a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. READ MORE

  4. 22. Design and Analysis of Highly Linear Integrated Wideband Amplifiers

    Author : Henrik Sjöland; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; nonlinearity cancellation; intermodulation distortion; RF amplifiers; IF amplifiers; audio amplifiers; power amplifiers; wideband amplifiers; analog integrated circuits; low voltage; amplifiers; distortion; bipolar; Electronics; Elektronik;

    Abstract : This dissertation deals with techniques for designing integrated amplifiers with high linearity. Amplifiers with operating frequencies from Audio to RF have been built. An enhanced feedback configuration, capable of very low distortion, is presented. READ MORE

  5. 23. Early-Decision Decoding of LDPC Codes

    Author : Anton Blad; Oscar Gustafsson; Erik G. Larsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ECC; LDPC; communication; coding; decoding; low-power; Tanner; iterative algorithms; Electronics; Elektronik;

    Abstract : Since their rediscovery in 1995, low-density parity-check (LDPC) codes have received wide-spread attention as practical capacity-approaching code candidates. It has been shown that the class of codes can perform arbitrarily close to the channel capacity, and LDPC codes are also used or suggested for a number of important current and future communication standards.

  6. 24. Low power synthesis of BDD mapped circuits

    Author : Mikael Kerttu; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : Power consumption is an important design constraint for circuits used in portable devices. In this thesis an analytic approach to minimize the power dissipation of Binary Decision Diagram (BDD) mapped digital circuits is presented. READ MORE

  7. 25. Technology for acurate and low power measurements

    Author : Kirill Kozmin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : Modern measurement systems can be found almost in any part of everyday life. Measurement accuracy of such systems is a vital factor which often associated with the system's overall performance and costs. The accuracy of a system is closely related to the system's power consumption. READ MORE
