For Dick's paper, see:
<http://www.ko4bb.com/manuals/download.php?file=02_GPS_Timing/4_App_Notes_and_Articles/Zero_cross_detector_low_jitter_JPL_1990.pdf>
The idea is clear from the block diagram, if you don't want to read
the whole paper:

Oliver Collins published a paper expanding on this idea ("The Design
of Low Jitter Hard Limiters," 1996).

I concur with Rick's suggestions. I would also suggest Edson's 1953
text, "Vacuum-Tube Oscillators," which gives details on some concepts
that are often glossed over in later texts:
