  1. 1. PLL for 5G mmWave

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

    Author : Daniel Bakic; Jinzhuo Wu; [2020]
    Keywords : PLL; 5G-NR; RFIC; beamforming; 22nm FDSOI; charge pump; vco; loop filter; frequency divider; phase detector; phase noise; jitter; Technology and Engineering;

    Abstract : This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. READ MORE

  3. 2. Model-Based Design, Development and Control of an Underwater Vehicle

    University essay from Linköpings universitet/Reglerteknik

    Author : Adam Aili; Erik Ekelund; [2016]
    Keywords : Model; Design; Development; Control; Underwater; Underwater vehicle; BlueROV; ROV; Fossen; Modelling; Parameter Estimation; Prediction-error method; Extended Kalman filter; EKF; Feedback linearisation; Attitude controller; Angular velocity controller;

    Abstract : With the rising popularity of ROVs and other UV solutions, more robust and high performance controllers have become a necessity. A model of the ROV or UV can be a valuable tool during control synthesis. The main objective of this thesis was to use a model in design and development of controllers for an ROV. READ MORE

  4. 3. Investigation of a Closed Loop Modulator for Bluetooth Radios

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Henrik Talborn; [2001]
    Keywords : Technology and Engineering;

    Abstract : This rapport investigates the transmitter of the Ericsson Bluetooth radio. The open loop modulation scheme of the existing design is theoretically very simple but difficult to implement with available components. Frequency drift of the carrier is a common result of open loop modulation. READ MORE
