  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

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

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

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

    Abstract : 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.

  3. 3. 16 GS/s Continuous-Time ΣΔ Modulator in a 22 nm SOI Process : a Simulation and Feasibility Study

    University essay from Linköpings universitet/Tekniska fakulteten; Linköpings universitet/Elektroniska Kretsar och System

    Author : Eric Öberg; Gustav Kindeskog; [2018]
    Keywords : sigma delta modulator;

    Abstract : With a reference specification model in terms of 8 GS/s Sigma Delta Modulator in a 28 nm CMOS process consuming 890 mW, the purpose with this thesis is to construct a similar and simpler model but with higher specification demands. In a 22 nm SOI process with an input signal bandwidth of 500 MHz sampled at 16 GS/s with a power consumption below 2 W, the objective is to design a Continuous-Time Sigma Delta Modulator with verified simulated functionality on a transistor level basis.

  4. 4. Design and Implementation of a High Frequency Flyback Converter

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Author : Nisar Ahmad; [2014]
    Keywords : Flyback Converter; Quasi-Resonant Soft Switching Technique.;

    Abstract : The power supply designers choose flyback topology due to its promising features of design simplicity, cost effectiveness and multiple outputs handling capability. The designed product based on flyback topology should be smaller in size, cost effective and energy efficient. READ MORE

  5. 5. Relationships Between Skin Properties and Body Water Level

    University essay from KTH/Medicinsk teknik
