Nothing ! You should not believe one of us but try to become convinced.
Therefore, my recommendation again:
- Perform a dc-analysis and evaluate the slope of the curve
around the correct bias point. All axis, of course, scaled linearly.
- Then, perform an ac analysis. Check if the same bias point is used from the program !
- If there is no considerable capacitice effect in the circuit, in both cases the gain must be identical.
