Doctoral Thesis: Analog Mixed Signal Design with Focus on PLL/Frequency Synthesizer Circuits (f/m/div) - #2156258

The industrial doctorate at Infineon: Pursue a doctoral degree at a university and gain professional experience simultaneously - an ideal start for your career. Advance your research with us and profit from our vast network of doctoral candidates and the expertise of a university. Mentorship is handled by both professors and dedicated Infineon employees.

We are offering a doctoral thesis dealing with the design, development, and testing of a high-performance PLL that meets the demands of modern communication systems. The specific goals of the project include: 1.,,Investigating and analyzing the state-of-the-art PLL architectures and identifying areas for improvement. 2.,,Developing a novel PLL design that achieves high frequency stability, low phase noise, low power and fast locking time. 3.,,Implementing the designed PLL in 28nm CMOS technology 4.,,Characterizing and testing the fabricated PLL to validate its performance. 5.,,Exploring techniques to improve the PLL's robustness against process, voltage, and temperature (PVT) variations.

The research is carried out in cooperation with the University of TU Munich and under the supervision of Prof. Dr. Brederlow, Chair of Circuit Design.

Job Description

The tasks within the thesis will consist of:

• Conducting a thorough literature review to identify the current state-of-the-art in PLL design
• Development and simulation of novel PLL architectures using CAD tools
• Design and layout of the selected PLL architecture
• Fabrication and testing of the PLL using suitable measurement equipment
• Analysis and interpretation of the measurement results to validate the PLL´s performance
  
  

The learnings out of the thesis will lead to:

• A novel high-performance PLL design that achieves improved frequency stability, lower phase noise, and faster locking time
• A comprehensive understanding of the PLL's behavior and performance under various operating conditions
• Contributions to the development of PLL design methodologies and techniques
