  1. 1. Superconducting gates for InP HEMTs

    University essay from KTH/Tillämpad fysik

    Author : Sebastian Alveteg; [2023]
    Keywords : Cryogenic electronics; HEMT; Superconductors; Applied Physics; Kryogenisk elektronik; HEMT; Supraledare; Tillämpad fysik;

    Abstract : The thesis examines the prospects of using the superconductor NbN as the gatemetal for an InP HEMT. A HEMT or High Electron Mobility Transistor is aheterostructure transistor engineered to reach very high electron mobility. InPHEMTs are used as cryogenic Low Noise Amplifiers (LNAs), which have increasedin demand as quantum computing is scaling up. READ MORE

  3. 2. Hidden behind the pandemic: A study on the effects of the COVID-19 restrictions on dissent

    University essay from Uppsala universitet/Institutionen för freds- och konfliktforskning

    Author : Cecilia Maria Borella; [2022]
    Keywords : State repression; COVID-19; Dissent; Philippines;

    Abstract : This thesis aims to address how COVID-19 restrictions affected dissent events in autocracies and electoral autocracies. To do so relies on the combination of the grievances and resource mobilization theories. READ MORE

  4. 3. A Modular Approach to Design and Implementation of an Active GNSS Antenna

    University essay from Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

    Author : Ulrik Hecktor; [2022]
    Keywords : GNSS; RTK; circular patch antenna; LNA; stacked patch antenna;

    Abstract : This master’s thesis describes the design, implementation and testing of an active antenna intended for use with global navigation satellite systems. The active antenna is composed of two major parts, a dual-band circular patch antenna and a dual-band low-noise amplifier. To streamline the design process, a modular solution was adopted. READ MORE

  5. 4. Evaluation of Discrete-Time Wideband Receivers for NB-IoT

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

    Author : Magnus Wasting; [2021]
    Keywords : Discrete; time; filter; NB-IoT; Charge; Sharing; CMOS; Technology and Engineering;

    Abstract : A receiver that covers several RF bands requires multiple front-end filters which increases the cost in terms of components and/or board/silicon area. Front-end filters assist a receiver to withstand interference at multiples of its down-conversion frequency. READ MORE

  6. 5. Methods of self-interference cancellation in full duplex telecommunication systems

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Henrik Erlandsson; Viktor Sköldheden; [2021]
    Keywords : telecommunication; full duplex; self-interference cancellation; electronics; wireless communication; power amplifier;

    Abstract : With the wireless technology evolving quickly, so does the demand of speed and efficiency. This makes the companies look for new and better ways to improve the current systems. One way of improving the present systems would be to employ Full Duplex Technology. READ MORE
