Jack - you rock - Adam was the name I was recalling, but I could not think of his last name. Thanks!

IIRC Adam went into industry after his PhD, and I'm not sure where this work got to or whether or not Mike continued to pursue this line of research. It would appear you can get his PhD here -- https://ora.ox.ac.uk/objects/uuid:8ace9e68-d8e7-4f1d-b6c9-13853eecbd47 Decending even deeper into my memory, I believe Curtis Mead did a similar thing to create samplers for a detector on an optical telescope (and gave a great talk at the 2010 CfA CASPER workshop). Edit: now I've found his thesis at http://seti.harvard.edu/grad/cpdf/mead_thesis.pdf I see he used standard LVDS inputs, not the MGTs.
