Ch06 Topic 09 - Worked 12 V MOSFET Bias Design
==============================================

Purpose
-------
Design a complete common-source DC operating point from a current/headroom target rather than from a guessed gate voltage.

Open in RFspice
---------------
1. Open ACDSPICE_Ch06_T09_Worked_MOS_Bias.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 FET models supplied with this course are educational representative models. They are intended to teach parameter-to-circuit relationships. Threshold voltage, IDSS, transconductance and capacitance vary substantially in real devices, so use the selected manufacturer's current datasheet and production SPICE model for final hardware correlation.
