  1. 21. Design of Two 28 GHz Doherty Power Amplifier Topologies with Vertical In(Ga)As Nanowire Transistors

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Simon Olson; Lucas Nilsson-Villoresi; [2020]
    Keywords : Doherty; PA; DPA; 28 GHz; Power amplifier; nanowire; transistor; In Ga As; Technology and Engineering;

    Abstract : In this Master’s thesis, two different 28 GHz Doherty power amplifiers (DPAs) are designed, for high power added efficiency (PAE), in the common source (CS) and cascoded topology respectively. The results are analyzed and compared between the two approaches. READ MORE

  3. 22. Execution time optimisation of a physics engine

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jimmy Lundberg; [2020]
    Keywords : Physics engine optimisation;

    Abstract : This paper contains several suggestions of improvements for an existingin-house physics engine. It treats subjects such as mathematical simpli-fications, data dependencies, branching, broad phase collision detectionand data-oriented programming. The suggested improvements are testedwith two devices, a Samsung Galaxy A6 running on a ARM Cortex-A531. READ MORE

  4. 23. Nanowire based mm-wave LNA and switch design

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Andreas Grenmyr; [2020]
    Keywords : LNA mm-wave RF switch nanowire MOSFET; Technology and Engineering;

    Abstract : In this work, two LNAs operating at a frequency around 83 GHz and 110 GHz, for satellite- and 5G applications respectively, have been designed, using vertical InGaAs nanowire transistors. In addition, a switch operating at a frequency around 110 GHz has been designed. READ MORE

  5. 24. Design of a Size Reduced Antenna Array for Angle of Arrival (AoA) Estimation for BLE 5.1

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Felix Långberg; Jonas Thurborg; [2020]
    Keywords : Antenna; Array; Bluetooth; 5.1; Angle of arrival; optimization; Technology and Engineering;

    Abstract : Bluetooth low energy (BLE) 5.1 allows for Angle of Arrival(AoA) measurements which in turn requires antenna arrays to be used. These arrays must be low power which results in that an efficient switching pattern is applied and for greater field of view good omnidirectivity is necessary. READ MORE

  6. 25. On the Design of CMOS Integrated LMBA

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Samji Srivatsa; [2020]
    Keywords : LMBA; PA; Lumped Couplers;

    Abstract : In this present world there is a huge requirement for high data rates and less powerconsumption in mobile networking. To achieve this one need to build a highly efficientpower amplifiers which is the most power consuming component in transmitterfront end. READ MORE
