  1. 1. Damping of sub-synchronous control interactions with a STATCOM : Wind farms & series compensated power lines

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Leonardo Alvarez Urrutia; [2022]
    Keywords : Sub-Synchronous Control Interactions; Power Systems; STATCOM; Network Stability; Doubly-Fed Induction Generator; Impedance-Based Stability Analysis;

    Abstract : The power converter is one of the key components in power system applications such as high voltage direct current (HVDC) systems and the grid connection of intermittent sources such as wind and solar power. However, the increased penetration of converter-based generation introduces challenges, such as sub-synchronous interaction between the converter control system and the grid. READ MORE

  3. 2. Comparator Design for High-Speed ADCs

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Pelle Lund; [2022]
    Keywords : comparator; high speed adc; adc;

    Abstract : As wireless communication is ever-evolving, demanding higher data speeds, the requirementsincrease for the ADC, and the requirements for the comparator, which is one of the mainbuilding blocks, increase as well. The primary purpose of the comparator is to compare twovoltage levels and provide a logic output. READ MORE

  4. 3. Design and Verification of An Energy-Efficient Edge-Pursuit Comparator

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

    Author : Haiqin Xie; [2022]
    Keywords : analog to digital converter ADC ; SAR; comparator; edge-pursuit comparator EPC ; edge-pursuit comparator enhanced with capacitor EPCC ; energyefficient.; analog till digital omvandlare ADC ; SAR; komparator; edge-pursuit komparator EPC ; edge-pursuit komparator förbättrad med kondensator EPCC ; energieffektiv.;

    Abstract : With the rapid development of mobile communication, sensors, and biomedical in recent years, the demand for accurate data information, highquality audio and image has become much more significant, which requires a high-precision Analog to Digital Converter (ADC) to process weak analog signals. As one of the core modules of ADC, the comparator’s precision, speed, stability, and noise play a key role in the performance of the whole circuit. READ MORE

  5. 4. Temperature Compensation in CMOS Ring Oscillator

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Xiaohua Wei; Dingyufei Zhang; [2022]
    Keywords : Current Starved Ring Oscillator CSRO ; Temperature compensation; Supply voltage compensation; Stable frequency; Digital controlling; Phase Frequency Detector PFD ; Dynamic comparator; Bidirectional counter; Charge pump CP ; Frequency divider; Power consumption; AMS 0.35 um; EDA tool Cadence;

    Abstract : A digital system is often required to operate under a specific frequency. A ring oscillator can be helpful in this circumstance because it can generate a signal with a specific frequency. However, a ring oscillator is also sensitive to the environment temperature. READ MORE

  6. 5. A design of a 100 MS/s, 8-bit Pipelined ADC in CMOS

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

    Author : Shen Zhang; [2021]
    Keywords : Technology and Engineering;

    Abstract : The thesis focuses on designing and simulating an 8-bit high-speed fully differential pipelined Analog to Digital Converter (ADC) in the 65nm Complementary Metal-Oxide-Semiconductor (CMOS) technology by using the software Cadence Virtuoso. The aim is to increase the operation speed of the ADC for communication systems without reducing the performance, in the meantime, the low power consumption and the low complexity should also be required when considering future implementation.
