1. Calculate RGIVin(V) based on Pout_RGI.
2. Calculate four points of the Vout(V) based on Pout.
3. For each RGI_xpt value, pick the RGIVin(V) from the RGI delta sweep and the Vout(V) from the alignment sweep. These four pairs of data form four points on an RGIVin vs Vout plane.
4. Scale RGIVin(V) and Vout(V) to 0~255. Get the relationship between (RGIVin, VCC, and Vout).
5. For each point, there is corresponding AMAM curve that goes through that point.
6. Find four points data of n-dB compression (RGIVin_n, VCC, and Vout_n) on the four curves. The M-Line goes through these four points.
7. Get the relationship between RGIVin_n(V), Vout_n(V), and VCC_n(V) for four data sets of n-dB compression point.
8. Calculate each point of (Vin, VCC, and Vout) in M-Line.
9. Convert (Vin, VCC, and Vout) to (rgi, bias, and Pout) for M-Line table.
