    Nyckelord :THEMIS EFI; transfer function; sheath impedance;

    Sammanfattning : In March 2007 five satellites were launched as part of the NASA mission THEMIS. The aim of the mission is to answer the unknown questions regarding the onset of substorms. THEMIS data has also been used within other research fields. LÄS MER

  3. 12. Drivförstärkare : Bredbandig drivförstärkare med hög verkningsgrad

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för fysik och astronomi

    Författare :Oskar Kristoffersson; [2011]
    Nyckelord :;

    Sammanfattning : This report present the design and manufacturing of a wide-band driver amplifier placed in radar module for airborne applications. The major goals for the amplifier were a high efficiency and to deliver a predefined output power. To reach the second goal an additional preamplifier had to be constructed. LÄS MER

  4. 13. Analysis of noise and offset in the comparator of ananalog-to-digital converter

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Annie Rydholm; [2008]
    Nyckelord :Analog-to-digital conversion; comparator; offset; noise;

    Sammanfattning : Since digital system has become very common today it is important to have good interfaces in between the analog and digital domain. This puts high demandson the analog to digital converter. It is therefore important in the design of theanalog to digital converter to reduce noise and offset as much as possible. LÄS MER
