Last week I completed the characterization of the “fully digital” TDC, Stephan Wiederkehr’s design. In this link there is the report, which I embed here:
Just in case, the report is in this GitHub repo and the current version is in this commit.
This TDC design “competes” against the “semi analog” design of Beat, which I studied in this post.
Now I am working in the presentation of these results (fully digital and semi analog) in the TIPP 2021 conference.
