  1. 1. Effect of active load on III-V NWFET Double-Balanced Gilbert Cells

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Pontus Arvidsson; [2016]
    Nyckelord :NWFET; active load ; Current bleeding ; Gilbert Cell ; 60GHz; Mixer; Master’s Thesis ; Cadence.; Technology and Engineering;

    Sammanfattning : Abstract A center point in the transistor research is to find a successor to the silicon-based transistors that are mainly used in today’s industry. III-V Field Effect Transistors (FET) have been the transistor of choice for many researchers for a long time but other options are interesting as well. LÄS MER

  3. 2. LOW COST ULTRA WIDEBANDRADAR FOR HUMAN PROTECTION

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Carlsson Hampus; Öhlund Martina; [2015]
    Nyckelord :UWB; pulse generator; gilbert cell; low cost; high frequency;

    Sammanfattning : The majority of the UWB radars available on the market today are expensive and often closed forfurther development due to proprietary rights. Therefore it is difficult to fully understand and adaptthe functionality of an available UWB system to fit one’s needs. The consulting-firm Addiva purchasedan UWB radar to be used in a safety system.

  4. 3. Simulations of III-V NWFET Double-Balanced Gilbert Cells with an Improved Noise Model

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Niklas Lindblad; [2013]
    Nyckelord :Technology and Engineering;

    Sammanfattning : III-V nanowire transistors might provide a mean for extending Moore’s law, by overcoming the scaling limitations ultimately facing planar silicon CMOS. These high frequency capable transistors with cut-off frequencies in the terahertz regime are suitable for radio communication. LÄS MER

  5. 4. Design of Millimeter-wave SiGe Frequency Doubler and Output Buffer for Automotive Radar Applications

    Magister-uppsats, Institutionen för systemteknik

    Författare :Amjad Altaf; [2007]
    Nyckelord :Automotive Radar; VCO; Frequency Multiplier; SiGE; ACC; Millimeter-wave;

    Sammanfattning : Automotive Radars have introduced various functions on automobiles for driver’s safety and comfort, as part of the Intelligent Transportation System (ITS) including Adaptive Cruise Control (ACC), collision warning or avoidance, blind spot surveillance and parking assistance. Although such radar systems with 24 GHz carrier frequency are already in use but due to some regulatory issues, recently a permanent band has been allocated at 77-81 GHz, allowing for long-term development of the radar service.
