Ch12 Topic 10 - Feedback-Stabilised Discrete Amplifier
======================================================

Purpose
-------
Close a global voltage-feedback loop around a transistor differential stage and verify gain desensitivity to device parameters.

Open in RFspice
---------------
1. Open ACDSPICE_Ch12_T10_Discrete_Feedback_Amplifier.rfspice.json.
2. Run the analyses already entered in the Analysis box.
3. Plot the nodes/currents named in expected_results.txt.
4. Compare the result with the hand calculation before changing values.

Model note
----------
The op-amp macromodels are deliberately transparent teaching models. For hardware correlation use the selected manufacturer's current datasheet and vendor SPICE macromodel.
