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

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

Watch this space... it's getting simpler and simpler as I convert device-level to behavioral... made great progress yesterday whilst awaiting wife at beauty parlor ;-) ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

>:-} 29 years ago, when the first daughter was wed, I agreed to "take the gray out", but have not done so since. I'm au naturel, and subject myself only to an occasional hair cut... usually I just hack some of it off myself with the sheep shears ;-) ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

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

Looks good. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

LTspice doesn't seem to have a level 7 BSIM3.2, although it meekly accepts "level=7", and digests all parameters, except Is. Is *is* accepted in level 1 thru 3. Frequency vs. Vc curves don't match datasheet curves, BTW, on further playing. Using 300k/39pF, frequency range is low. Likewise 300k/0.1uF 3k/0.1uF shape not bad, but still low. 3k/39pF shape wrong. (Comparison with ON Semiconductor 74HC4046 published data.) Detailed plots when they churn out. -- "Design is the reverse of analysis" (R.D. Middlebrook)
