Hello,
I am trying to model an op amp which changes the amplitude of the output of an LVDT that I have already modeled. The LVDT is modeled using the magnetic field physics and I have tried adding an electric circuit physics to model the op amp. There are two other electric circuit models that I am hoping to replace with this model which I have not removed yet. I imported the SPICE netlist provided from Texas Instruments who make the op amp I'm using. However, an error pops up: device FB refers to missing device POLY. I'm not sure how to rectify this error, any assistance would be appreciated. I have attached my file with the error and the TI SPICE file.
Thank you, Michelle
