IPE 15-20 Masterthesis: Development of a novel Time-to-digital converter FPGA architecture using machine learning

Organizational unit

Institute for Data Processing and Electronics (IPE)

Job description

Time-to-Digital converters (TDCs) are widely used in high-energy physics and other applications that require precise time measurements. Field programmable gate arrays (FPGAs) can be used to realize TDCs without any external circuits. Current TDCs are based on tapped delay lines (TDL). There are two major issues with the design of this delay lines in FPGA. Delay bins are not uniform and strongly dependant on temperature and voltage level. To compensate this effect and improve the time resolution the bin widths must be calibrated online. This thesis focusses on a novel TDC architecture where the digital electronics, employed for both decoding and on-line calibrations, is replaced by a machine learning algorithm, which extracts the digital information directly from the TDLs. The goal is to measure time-of-arrive and length of pulses with picosecond time resolution.

Starting date

as soon as possible

Personal qualification

Your tasks:

  • Study the current TDC architectures
  • Develop a novel TDC architecture with machine-learning with an ZYNQ US++
