    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Tommy Lundberg; [2023]
    Nyckelord :Digitally Controlled Oscillator; All-Digital Phase Locked Loop; Oscillator; Low Phase Noise; Class-C oscillator; Dual-Core; Dynamic BiasingCircuit; Digitalt Styrd Oscillator; Digital PLL; Lågt Fasbrus; Klass-C Oscillator; Dubbelkärnig; Dynamisk Bias-Krets;

    Sammanfattning : Following the rise of Internet of Things (IoT), or just the technological advancements and expectations in a world where the things are or will be connected, new demands are put on Integrated Circuit (IC) for wireless connectivity. The use cases seem endless; smart home, healthcare, entertainment, and science are all areas that can benefit from connectivity of low power electronics. LÄS MER

  3. 2. Characterisation of the LYCCA Double-Sided Silicon Strip Detectors

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Marwan Mohamed; [2023]
    Nyckelord :DSSD LYCCA HISPEC FAIR Characterisation; Physics and Astronomy;

    Sammanfattning : The goal of this thesis work is to describe the methods used and perform comprehensive testing of the Double-Sided Silicon-Strip Detectors (DSSD) prior to their implementation in the Lund-York-Cologne CAlorimeter (LYCCA) detector. In the framework of this project, the DSSD characterisation was carried out to ensure specification compliance prior to their "in-kind contribution" delivery to the HISPEC experiment at the NUSTAR collaboration.

  4. 3. Design of a Differential Cross-Coupled Power LC Oscillator with ASK Modulation

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Sanjay Sarker; [2023]
    Nyckelord :Cross-coupled LC Oscillator; Amplitude Shift Keying ASK Modulator; Spiral Inductor; MIM Capacitor; Current Mirror Switching;

    Sammanfattning : Rapid growth in the field of communications industry has led to newer opportunities and challenges in the design of CMOS based monolithic integrated circuits. ASK modulators are a class of digital modulators which are known for their relative simplicity of implementation for low cost applications in the industrial and biomedical domains. LÄS MER

  5. 4. Cold amplification and fiber coupling of a super-conducting nanowire single-photon detector

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Stéphane Cohen; [2022]
    Nyckelord :Applied Physics; Tilllämpad fysik;

    Sammanfattning : Single-photon detectors are an essential tool for quantum photonics: one can harness the quantum properties of single photons for quantum communication as well as use the detectors in low illumination applications.Superconducting nanowire single-photon detectors offer high detection efficiency over a widerange of wavelengths, low dark counts, and a good timing resolution compared to single-photonavalanche diodes.

  7. 5. Design of LED setup for measuring tandem solar cell subcell J-V behaviour

    Kandidat-uppsats,

    Författare :Kristina Bergström; Mohammed Nour Kamalmaz; Erik Lindvall; [2022]
    Nyckelord :Tandem solar cell; LED; background light; bias; arduino; processing; subcell;

    Sammanfattning : The need to accurately measure multi-junction (MJ) tandem solar cells' subcell current-voltage characteristics is increasing due to the vital information they provide about the efficiency, stability, and longevity of the cells. These measurements are rather difficult compared to their counterpart single-layer solar cell measurements. LÄS MER
