1. A Low Noise Digitally Controlled Oscillator for a Wi-Fi 6 All-Digital PLL
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
2. A Digital Phase-Locked Loop for Frequency Synthesis using an Adaptive Pulse Shrinking TDC
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : This thesis investigates a new type of Phase-Locked Loop (PLL) architecture which combines a phase/frequency detector (PFD) and a digital loop filter. The quantization is done by a time-to-digital converter which continuously shrinks the pulse coming from the PFD and registers how far it propagates. LÄS MER
3. A digital integer-N PLL architecture using a pulse-shrinking TDC for mmWave applications.
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : With the move of the broadband cellular network towards 5G taking off and the preparatory work on 6G and beyond starting, the need for low-complexity, low-power, and high-performance frequency synthesis using Phase-Locked Loop (PLL)s increases. As we get deeper into the mm-wave frequencies and push towards frequencies in the order of 50-70 GHz design challenges with existing PLL architectures, such as limited technology scaling and limited in-band noise performance become more apparent.

4. Closed-loop control and data- recording of a modular-multilevel converter (MMC)
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI. LÄS MER
5. Frequency Stability of Power Electronic Based Power System with 100% Renewable Energy.
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The modern power system is aiming to progress away from conventional synchronous machine based power generation towards converter dominated system that leads to extensively high penetration of renewable energy such as wind and PV. This transition of modern power system toward converter based renewable energy comes with new challenges as the conventional synchronous generation is being replaced by converter based power system (CBPS).
