I am trying to simulate a low-passing filter in Eschema 5.99 + NGSpice 31, the schematic is attached. I have some question:
- I didn’t found a current source controlled by current on Spice library of Eeschema. Is it missing?
- The Spice is warning me that it didn’t find the capacitor or op. amp. circuit. Did I used the wrong library?
