using 3rd party spice model proteus
Hi
It is quite straightforward, I think it is easiest if you check example in help.
Proteus uses SPICE3F5, I am not sure you can do all simulations in lite version.
In ISIS go here:
Help-Sample Designs- GRAPH BASED SIMULATION SAMPLES- there you can open
SPICE1.DSN Example of how to use a 3rd party SPICE model for an IC.
SPICE2.DSN Example of how to use a 3rd party SPICE model for a transistor.
You can also run them directly from samples folder.
You can always start with editing the SPICE1 and use another opamp, this way you can verify you do it right.
Good luck and ask again if you run into problems.
