Hello Folks,
See the scope plot and excerpt from the ON Semi datasheet for the
CD4060. The blue trace is at the node RS/Rtc/Ctc, the yellow trace is
at pin 9 which is an output.
Why is there sag at the end of each phase? Rs is 500K and Rtc is 100K.
I mean, that shouldn't be any load to write home about even for a CD
series part.

It looks like normal behavior for the gaye oscillaotr! AS the feedback
signal apporahes the logis threshold, the front end of the logic gate
leaves the "digital" realm, where we only have cut off and saturation,
and enters......... the analog linear zone. so the out ut then has a
gain of about *;! for a slwly vaying input...till the thershaold is met,
the devcie swicthes.. the inout signal are largelry seprated
(magnitude...and you're back in the digital "realm".

I knw exactly how to sqaure this up too
Well, it's squared up alright but the cross-current's net contribution
to the total battery consumption is painful.
That's why my 3-inverter version is so much better... speed-up thru
the threshold region.
