  1. 1. Advanced III-Nitride Technology for mm-Wave Applications

    Författare :Anna Malmros; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ohmic contact; passivation; InAlN; high frequency performance; GaN; InAlGaN; HEMT; electron trapping;

    Sammanfattning : Within wireless communication, there is a continuously growing need for more bandwidth due to an increasing number of users and data intense services. The development within sensor systems such as radars, is largely driven by the need for increased detection range and robustness. LÄS MER

  3. 2. Efficient mm-Wave Transmitter Design in CMOS Technology

    Författare :Therese Forsberg; Institutionen för elektro- och informationsteknik; []
    Nyckelord :CMOS; transmitter; analog; integrated circuits; millieter-wave;

    Sammanfattning : An increasing demand of higher data rates in wireless communication forces the industry to look to higher frequencies to find the required bandwidths. This thesis is about analog transmitters in CMOS for millimeter-wave communication, and it focuses on improving power amplifiers and frequency generation circuits, and increase their efficiency.
