  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

  2. 22. Towards a method for antenna impedance tailoring through shapeoptimization, with a bound on the associated cost-function

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Cem Kesici; [2020]
    Keywords : ;

    Abstract : Over the last years, there has been an interest in designing antennas that operateat higher frequencies. In most applications, these antennas work jointly withPower Amplifiers. However, most commercial Power Amplifiers have a nonstandardoptimal load-pull impedance in their optimal operating frequencies. READ MORE

  3. 23. Low Power Pre-Distorter Design For 5G Radio Using Machine Learning

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

    Author : Sumeeth Diddigi Kulkarni; Di Wang; [2020]
    Keywords : Technology and Engineering;

    Abstract : A Power Amplifier (PA) is an essential electronic component in all microwave and millimeter-wave applications and, more specifically, in any transmitting system where the level of input power signal needs amplification to the desired level.Linearity and high efficiency are of utmost importance in PAs.

  4. 24. Ring amplifiers for high speed pipeline assisted SAR ADCs

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

    Author : Johan Holmstedt; [2020]
    Keywords : ADC SAR RAMP ring amp residue amplifier PVT; Technology and Engineering;

    Abstract : This thesis contains a review of published ring amplifier topologies. It is suggested to split the input stage of the ring amplifier into two. In this way, a robust ring amplifier can be designed without stacking the transistors in the second stage of the ring amplifier, boosting its speed properties. READ MORE

  5. 25. 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
