Analog Integrated Circuits

Research Interests

  • Low-noise, high speed oscillators
  • high-precision time-to-digital converters (TDC)
  • All-digital phase-locked loops (ADPLL) for high frequencies (> 50 GHz)
  • Electronic Design Automation with a focus on layout generation

Thesis Offerings

Please see our thesis offerings on our website or directly contact me with any topics that you might be interested in.

Patrick Kurth (nee Schulz) received the B.Sc. and the M.Sc. of electrical engineering in 2015 and 2017, respectively, from the Technische Universität Berlin.
During his studies he worked for nine months at the Mikroelektronik Anwendungszentrum im Land Brandenburg (MAZBr) as circuit and layout designer. In his master thesis, he studied phase noise properties of different oscillator topologies and developed an low-noise oscillator based on active inductors.
He joined the chair of mixed-signal circuit design in november 2017.

Abstract We report high-frequency polarization self-modulation (PSM) in high speed vertical-cavity surface emitting lasers (VCSELs) connected to the stress-induced birefringence in oxide-confined aperture VCSELs. Polarization oscillations up to 45 GHz were captured. We analyze the far and the near field of the device and show how the fiber-coupling conditions induce optical feedback, affect emission properties of the device and influence the polarization switching phenomenon. In conditions where the PSM was suppressed, we demonstrate NRZ high-speed multi-mode fiber data transmission up to 90 Gbit/s.
