  1. 1. A Low Noise Digitally Controlled Oscillator for a Wi-Fi 6 All-Digital PLL

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tommy Lundberg; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Simulation, Design, and Implementation of a Narrow Linewidth Ytterbium Fiber MOPA System at 1087 nm

    University essay from KTH/Tillämpad fysik

    Author : Berkay Efilti; [2023]
    Keywords : Applied Physics; Laser Physics; Fiber Lasers; Fiber Amplifiers;

    Abstract : This thesis focuses on simulating, designing, and characterizing a narrow-linewidth continuous-wave (CW) Ytterbium (Yb) master oscillator fiber amplifier (MOFA) system. The primary goal was to achieve a watt-level output at 1087 nm with a narrow 1 GHz linewidth, making the MOFA well-suited for serving as a pump source in Terahertz (THz) generation experiments.

  4. 3. A digital integer-N PLL architecture using a pulse-shrinking TDC for mmWave applications.

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Richter; [2023]
    Keywords : Phase-locked-loops; All-digital Phase-locked-loops; Time-to-digital converters; 5G and beyond; Radio-frequency design; Fas-låsd-loop; Helt-digital fas-låst-loop; Tid-till-digital-omvandlare; 5G och framtiden; Radio-frekvens design;

    Abstract : With the move of the broadband cellular network towards 5G taking off and the preparatory work on 6G and beyond starting, the need for low-complexity, low-power, and high-performance frequency synthesis using Phase-Locked Loop (PLL)s increases. As we get deeper into the mm-wave frequencies and push towards frequencies in the order of 50-70 GHz design challenges with existing PLL architectures, such as limited technology scaling and limited in-band noise performance become more apparent.

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

    University essay from Linköpings universitet/Elektroniska Kretsar och System

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

    Abstract : 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. READ MORE

  6. 5. Distortion and attenuation free gain-assisted Superluminal Propagtion in a Rare-Earth Doped Crystal

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Antonius Johannes Renders; [2023]
    Keywords : Fast Light; Superluminal Propagation; Negative group velocity; Rare earth; Physics and Astronomy;

    Abstract : A light pulse that travels through a narrow spectral window, i.e. a frequency range of low absorption, within a strongly absorbing frequency range will be delayed due to strong dispersion. READ MORE
