Apparently I've already measure the PN of a comparator driving a few ACMOS buffers.

Attachment (slightly over 100kB) compares this with HX2410(Holzworth).

My intention at the time was probably to feed it a signal comparable to the lowest levels commonly seen from typical 10 MHz sources. It may or may not do better at higher input levels, but it'll obviously get worse once the level goes below a certain point.
