Here is my first pass at the HC4046 (VCO portion only), now in LTspice
format...

Looks pretty good to me, apart from LTspice not understanding "IS" parameter.


Sometimes LTspice throws up over what it's supposed to know... IS is a
common parameter for MOS devices... defines the body diode.


Plot of frequency versus control voltage attached


Looks good.
