I have been notified by Helmut Sennewald that the LTspice encryption process hides the node sequence. So please revisit... http://www.analog-innovations.com/SED/HC4046_SUB.zip 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 >:-} ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 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.

Looking >forward to trying it out!My aim is to make the model as close to the silicon as possible. For amusement, since it had been mentioned, I'm also doing the uA741 at the same time. It may be done tomorrow or Monday, since it's rather easy. The 4046 will take awhile to get all the pieces working together. ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 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.

The 74HC4046 was mentioned multiple times. I am supplying a model that I presume will behave more accurately. Since the 74HC4046 is complex, I am asking, as I go, "Does this portion fit?" If no one really wants a good 74HC4046 model I'll go do something else. ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 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.

As Phil and you pointed out its pretty crappy. -- Failure does not prove something is impossible, failure simply indicates you are not using the right tools... nico@nctdevpuntnl (punt=.) --------------------------------------------------------------
