  1. 1. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Klas Junskog; [2023]
    Nyckelord :oscillators; mm-wave; radar; Technology and Engineering;

    Sammanfattning : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. LÄS MER

  3. 2. Circuit design and hardware implementation of an analog synthesizer

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Olle Murhed; [2023]
    Nyckelord :synthesizer; analogue; circuit design; sound; sound synthesis; oscillator; VCO; filter; amplifier; sequencer; control voltage; breadboard;

    Sammanfattning : Since the heyday of analogue synthesizers in the 70's, they have largely been replaced by digital hardware and software synthesizers. However, in recent years, there has been a revival in analogue designs, possibly due to its ``warmer" sound. LÄS MER

  4. 3. Analysing Green Purchasing Behaviour Inconsistency : an example from voluntary carbon offset program

    Master-uppsats, SLU/Dept. of Economics

    Författare :Bintang Rahmadi; [2022]
    Nyckelord :Behaviour; Attitude; VCO; Inconsistency; Green; Purchasing; Carbon;

    Sammanfattning : This research investigates current and explores new factors contributing to green purchasing behaviour inconsistency using qualitative method and iterative grounded theory approach. Green purchasing behaviour inconsistency derived from the behaviour-attitude gap theory that occurs within different context of consumer behaviour cases, thus this research tries to answer: “What are the factors that cause green purchasing behaviour inconsistency?” using Voluntary Carbon Offset (VCO) program as an example.

  5. 4. Digital Control of a VCO for Radar Applications

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Martin Alumets; Mattias Evaldsson; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Radar systems have been around since the early 20th century, and technology is advancing at an ever-increasing speed. This has led to great achievements in radar development, which have expanded the technology's area of use. LÄS MER

  7. 5. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Hamid Yadegar Amin; [2020]
    Nyckelord :5G Phased array mm-wave FR2; Technology and Engineering;

    Sammanfattning : The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and improving SNR at higher spectra, multi-antenna systems have gained an inevitable role in developing such radios. LÄS MER
