Design Notes

VSS NL_MDIF model

This project demonstrates:

1. The use of the VSS NL_MDIF block to read in a P2D file

2. The use of  SWPVAR blocks to sweep the two vairables, vgate and temp, found in the P2D file.

3. The use of a SWPVAR to sweep the power level of the signal driving the NL_MDIF model

RFB measurements are used to measure AMtoAM and NF.

NL_MDIF uses a disk based file. The file used by the block must be placed in the same directory as the project. Please read the element help for NL_MDIF.
