I have been notified by Helmut Sennewald that the LTspice encryption
process hides the node sequence. So please revisit...

for a corrected version.
This is just the VCO portion for now, and just the variable part;
suitable only for LTspice.
Please try it out and let me know your comments, etc.
Since I'm new to working with LTspice, please send me any error
messages, so I can refine my skills :-}
What upsets me most is that it's a copy of my 1965 design, the MC4024
(bipolar devices, oscillator core is PECL, TTL output). And they
bungled the copy :-( Unlike my original version, the CMOS version
dumps the capacitor is an uncontrolled manner, and the thresholds and
current mirrors are abominations of "engineering".

I love to cook with wine. Sometimes I even put it in the food.
