The upgraded version III had IIRC a resolution of ~25ps with
better than 100ps achieved. Eventhough the PICTIC III design is
a bit more involved than then II, it's still relatively simple
(it uses more stable current sources, buffer opamps, external
ADCs and an active offset compensation scheme).
Hmm, sounds interesting ...
Is there a PICTIC III schematic somewhere?
I don't have any. All I have is some description of the changes
Richard did to the PICTIC II in a couple of private mails.
