Look at the LPRO manual. They have a couple of circuits that uses a single CMOS gate with a capacitively coupled input. Wenzel has some very similar circuits on their web site (search for "Wenzel squarer").
My HP-531xx counter calibrator board uses on as the input squarer (with a 74HCT86 as the gate). I measured the ADEVs of the output and they were indistinguishable from the input. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
