  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. 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. 3. Electrically Modified Quartz Crystal Microbalance to Study Surface Chemistry Using Plasma Electrons as Reducing Agents

    University essay from Linköpings universitet/Kemi

    Author : Pentti Niiranen; [2021]
    Keywords : Plasma enhanced chemical vapor deposition; PECVD; Quartz crystal microbalance; QCM;

    Abstract : Metallic films are important in various applications, such as electric devices where it can act as contacts. In electrical devices, the substrate typically consists of silicon dioxide (SiO2) which is a temperature-sensitive substrate. READ MORE

  5. 4. Ring amplifiers for high speed pipeline assisted SAR ADCs

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

    Author : Johan Holmstedt; [2020]
    Keywords : ADC SAR RAMP ring amp residue amplifier PVT; Technology and Engineering;

    Abstract : This thesis contains a review of published ring amplifier topologies. It is suggested to split the input stage of the ring amplifier into two. In this way, a robust ring amplifier can be designed without stacking the transistors in the second stage of the ring amplifier, boosting its speed properties. READ MORE

  6. 5. Data communication and power supply on a two conductor system

    University essay from Uppsala universitet/Elektricitetslära

    Author : Tobias Andersson; Jonathan Toft; [2018]
    Keywords : two wire communication; power; data; RS-485; transmission; hardware platform; long distance;

    Abstract : This master thesis aimed to develop a prototype of a hardware platform which allowed digital communication as well as DC power to be transmitted over one pair of wires. The prototype was used as a pre-study for Axis Communications AB that wanted a bit rate high enough to transmit digital audio, as well as enough power to supply a set of speakers. READ MORE
