P3.7. PMOS Output Characteristic

Components


LabVIEW Computations

Linear Region

Active Region

Procedure

  • Install PMOS parameters from P3.6 into the Front Panel of PMOSoutput.vi. A given VSD sweep will halt at Chan0_out = 10 V. Set VSGstart(V) as necessary to obtain ID ≈ 100 μA for VSD in the active region. Verify that the measured data and SPICE calculation agree reasonably well. Write in you file path and save a data file for Mathcad. The file will contain the data points for the highest current output characteristic. Default Front Panel and save. These data will be used in the Mathcad analysis file.

  • With the data defaulted and saved in the graph of the VI, a data file can be obtained at a later time. From the Diagram of PMOSoutput.vi, click on XYtoDataFile.vi, copy the data from PMOSoutput.vi, and paste it into the Control Graph of XYtoDataFile.vi. Name the path and data file and run the VI. XYtoDataFile.vi is located in the User.lib in the LabVIEW folder. Therefore, it can also be opened from the Diagram of a VI under Functions>>User Libraries>>Dat_File.
