  2. 1. Digital Phase Locked Loops for Radio Frequency Synthesis

    Author : Ahmed Mahmoud; Integrerade elektroniksystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; PLL; DPLL; VCO; DCO; loop filter; DS modulator; phase noise; spurs; quantization noise; BBPD; TDC; DTC;

    Abstract : The demands for an ever higher data rate and a more varied functionality at minimal cost and power consumption have been the driving force behind most innovations in wireless communication systems. Intensive efforts have been made to develop Radio Frequency (RF) Integrated Circuits (ICs) and systems using low-cost Complementary Metal Oxide Semiconductor (CMOS) processes. READ MORE

  4. 2. On PLL Modeling and Design in Nanometer‐Scale CMOS

    Author : Anders Jakobsson; Shaofang Gong; Adriana Serban; Hannu Tenhunen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-locked loop; Frequency synthesizer; Calibration; Modelling; Quantized-state system; Phase interpolator; Sub-sampling PLL;

    Abstract : Integrated circuits play a vital role in our everyday lives, from wireless gadgets and multimedia players to sensors and processors that control vital infrastructure. Since most electronic circuits need a clean, stable clock or carrier to function, one of the most important components of integrated circuits is the phase-locked loop. READ MORE

  5. 3. Micro- and Millimeter Wave CMOS Beamforming Receivers

    Author : Andreas Axholt; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beamforming; CMOS; front-end; microwave; millimeter wave; phase-locked loop; phased-array;

    Abstract : The available bandwidth in wireless communication systems, such as the 802.11 family, is very limited. Together with the ever increasing data traffic, this causes problems. New possibilities are, however, available thanks to wide license-free bandwidth allocated at higher frequencies. READ MORE

  6. 4. On Deep Machine Learning Based Techniques for Electric Power Systems

    Author : Ebrahim Balouji; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deep Learning; Cable faults; phase locked loop; Flicker; Harmonics and Interharmonics; Reinforcement learning; Voltage Dip; Active Power filter; Machine Learning; Voltage fluctuation; Partial Discharges;

    Abstract : This thesis provides deep machine learning-based solutions to real-time mitigation of power quality disturbances such as flicker, voltage dips, frequency deviations, harmonics, and interharmonics using active power filters (APF). In an APF the processing delays reduce the performance when the disturbance to be mitigated is tima varying. READ MORE

  7. 5. Circuit Design for All-Digital Frequency Synthesizers

    Author : Muhammad Touqir Pasha; Mark Vesterbacka; Ted Johansson; Jacob Wikner; Darius Jakonis; Linköpings universitet; []
