  1. 1. EMC-Optimized Transparency: Reducing Electromagnetic Emissions in Surveillance Camera Domes

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Fabian Sondh; Erik Hansson; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Electromagnetic compatibility (EMC) is a crucial aspect to product development. Companies need to make sure their products live up to the standards that exists around the world. One way of reducing electromagnetic emissions is to shield the product, using some conducting material, for instance, copper. LÄS MER

  3. 2. Investigation of Analog Calibration Systems for Spurious Tone Suppression in Frequency Triplers

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

    Författare :Cristian Alexandru Ghihanis; Barath Copparam Santhanakrishnan Sudarsan; [2023]
    Nyckelord :Delay-Locked Loop; DLL; Edge-Combining; EC; EC DLL; Edge-Combining Delay-Locked Loop; spurious tone calibration; spurs calibration; spurious tones compensation; spurs compensation; Technology and Engineering;

    Sammanfattning : The market for Wi-Fi receiver designs for latest Wi-Fi standards, that cover RF bands in the 2.4 GHz, 5 GHz and 6 GHz spectrum, require increasingly stringent power consumption limitations as more of the market is driven towards battery-powered devices. LÄS MER

  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. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Marie Defives; [2022]
    Nyckelord :Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

    Sammanfattning : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. LÄS MER

  7. 5. Performance Evaluation of Cryptographic Algorithms on ESP32 with Cryptographic Hardware Acceleration Feature

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

    Författare :Qiao Jin; [2022]
    Nyckelord :Embedded systems; ESP 32; Cryptographic algorithms; Cryptographic hardware acceleration; AES; RSA; SHA-2; HTTPS; Inbyggda system; ESP 32; Kryptografiska algoritmer; Kryptografisk hårdvaruacceleration; AES; RSA; SHA-2; HTTPS;

    Sammanfattning : The rise of the Internet of Things (IoT) and autonomous robots/vehicles comes with a lot of embedded electronic systems. Small printed circuit boards with microcomputers will be embedded almost everywhere. LÄS MER
