Recently I've been exploring the TDC design space as these devices are a critical part of our experiments (I do spectroscopy of biological molecules). I'm currently (slowly) working on a FPGA TDC design (based on the PandaDAQ[1] and CERN's Spartan 6 TDC design) but it seems it will be non-trivial to get down to the 12 ns the commercial offerings provide (although at great cost). What would a discrete TDC design look like? Are there any designs in the open?
