PhD thesis (Sep 2012): Fundamentals of CMOS Single-Photon Avalanche Diodes
Promotor: Edoardo Charbon

Expertise: CMOS Single-Photon Avalanche Diodes

Themes: Quantum imaging sensors


Matthew Fishburn was a PhD student in the CAS group, with Prof. Edoardo Charbon, working on the EU MEGAFRAME project.

  • Worked on a small team that designed, simulated, laid out, and characterized a 160x128 SPAD-TDC array in a 130nm imaging process. The international team, a subset of MEGAFRAME project members, included individuals from four European universities, all located in different countries
  • Designed, simulated, laid out, and characterized multiple mixed-signal, semi-custom ASICs in a high-voltage, 0.35 micron CMOS process. Contents of ASICs include a 20ps time-to-digital converter, custom serializer, and custom singe-photon avalanche diodes. Characterization included: standard noise and light sensitivity measurements; a noise measurement during gamma-ray irradiation up to a dose of 300 kGy; a jitter measurement using a pulsed, class 3B laser; and a responsivity uniformity measurement using an optical microscope
  • Designed custom read-out systems for multiple mixed-signal ASICs. Read-out systems used computer workstations interfaced to commercial FPGA-based motherboards with custom daughterboards
  • Statistically modeled and analyzed the tradeoff between fill factor and timing resolution in digital silicon photomultipliers targeting positron emission tomography.
