  1. 6. PLL for 5G mmWave

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

    Author : Daniel Bakic; Jinzhuo Wu; [2020]
    Keywords : PLL; 5G-NR; RFIC; beamforming; 22nm FDSOI; charge pump; vco; loop filter; frequency divider; phase detector; phase noise; jitter; Technology and Engineering;

    Abstract : This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. READ MORE

  3. 7. Supercurrents in a Topological Josephson Junction with a Magnetic Quantum Dot

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Adam Szewczyk; [2018]
    Keywords : Majorana; Andreev; Keldysh; Josephson; density of states; quantum transport; topological superconductor; magnet;

    Abstract : The purpose of this master thesis is to investigate theoretically the influence of a nanomagnet on the Josephson effect displayed by phase biased point contacts consisting of topological superconductors. The device is modeled using the nonequilibrium Keldysh Green’s function technique. First, the Gor’kov Green’s functions are calculated. READ MORE

  4. 8. Redesigning a Locking System for a Rail Road Dumper

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Viktor Björnström; [2018]
    Keywords : Industrial design engineering; locking mechanism; rail road dumper; logistics; product development; prototyping; Teknisk design; låsmekanism; järnväg; dumper; logistik; produktutveckling; prototyp;

    Abstract : This report describes a master thesis in Industrial Design Engineering performed at Kiruna Wagon towards Luleå University of Technology in the spring of 2018. The task of the project is to develop a new locking mechanism to the doors of one of Kiruna Wagons planned product releases, the Side Dumper. READ MORE

  5. 9. Implementation of continuous filtering frequency comb Vernier spectroscopy for continuous acquisition of spectra in a flame

    University essay from Umeå universitet/Institutionen för fysik

    Author : Adam Edlund; [2017]
    Keywords : optical frequency comb; continuous filtering Vernier spectroscopy;

    Abstract : In this project laser absorption spectroscopy was performed on a flame in a Fabry-Pérot cavity, using an optical frequency comb. Optical frequency comb spectroscopy is a technique that allows broadband ultra-sensitive detection of molecular species in gas phase. READ MORE

  6. 10. Experimental Implementation of a Fiber Noise Cancellation System for Slow Light Laser Locking

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Partikel- och kärnfysik

    Author : Alexander Bengtsson; [2017]
    Keywords : Optical Fibers; Fiber Noise Cancellation; Laser Stabilization; Slow Light Laser Locking; Technology and Engineering;

    Abstract : An electromagnetic wave propagating through an optical fiber is sensitive to external disturbances, such as mechanical vibrations and temperature and pressure fluctuations, which add phase noise onto the wave. For high-precision frequency-based applications this phase noise has to be removed. READ MORE
