  1. 1. Test and Calibration of CUBES: a CubeSat X-ray Detector

    University essay from KTH/Fysik

    Author : Caroline Holmberg; [2022]
    Keywords : Applied Physics; Astroparticle Physics; Tillämpad fysik; Astropartikelfysik;

    Abstract : CUBES is an X-ray detector that will be placed aboard the KTH 3U CubeSat mission, MIST. Its purpose is to detect high energy X-rays as well as to test various components in a space environment. Two CUBES will be placed on the satellite. Each CUBES consists of a printed circuit board (PCB) with three multi pixel photon counters (MPPCs). READ MORE

  2. 2. Temperature Compensation in CMOS Ring Oscillator

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Xiaohua Wei; Dingyufei Zhang; [2022]
    Keywords : Current Starved Ring Oscillator CSRO ; Temperature compensation; Supply voltage compensation; Stable frequency; Digital controlling; Phase Frequency Detector PFD ; Dynamic comparator; Bidirectional counter; Charge pump CP ; Frequency divider; Power consumption; AMS 0.35 um; EDA tool Cadence;

    Abstract : A digital system is often required to operate under a specific frequency. A ring oscillator can be helpful in this circumstance because it can generate a signal with a specific frequency. However, a ring oscillator is also sensitive to the environment temperature. READ MORE

  3. 3. Statistical Analysis of Dark Counts in Superconducting Nanowire Single Photon Detectors

    University essay from KTH/Fysik

    Author : Anton Cakste; Martin Andrae; [2022]
    Keywords : Single-Photon Detector; SNSPD; Dark Counts; Quantum Random Number Generator; Afterpulsing;

    Abstract : In this paper we perform a statistical analysis of dark counts in superconducting nanowire single photon detectors (SNSPDs) with the end goal of creating a quantum random number generator (QRNG) using these dark counts. We confirm that dark counts are Poissonian for low bias currents and that no afterpulsing is present. READ MORE

  4. 4. FPGA Implementation of an Anonymization Algorithm

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

    Author : Niklas Kjellman; Rehenuma Tarannum; [2020]
    Keywords : FPGA anonymization privacy anonymization filter spacial filter; Technology and Engineering;

    Abstract : With the large amount of surveillance cameras in our public spaces there has been much discussion about their effects on privacy. Axis communications has an algorithm that tries to remedy this by making it hard to see who is in an image but still have it possible for a neural network to detect that there is a person present.

  5. 5. Design and Implementation of a 5.8 GHz superheterodyne FM Video Receiver

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

    Author : Carl-Johan Stålberg; [2019]
    Keywords : Superheterodyne Receiver; 5.8 GHz; FM;

    Abstract : This master thesis presents the design and implementation of a super heterodyne 5.8 GHz receiver system for wireless transmission of phase alternating line (PAL) composite video signals. The system is implemented using surface and hole mounted devices on four separate printed circuit board (PCB) stages. These stages include a 5. READ MORE
