LabVIEW Computations

Straight-line curve fit from active region data:

I_D = Slope · V_SD + I_Do

λ_p = Slope/I_Do k_p = I_Do/V_effp²

Procedure

• Lambda.vi is configured for Enable Data Base Access to read the data from PMOSoutput.vi. Lambda.vi can read all of the Front Panel information in PMOSoutput.vi when a log of the Front Panel has been obtained.
  
  
• From the Diagram of Lambda.vi, open PMOSoutput.vi. Obtain a data log of the Front Panel of the PMOSoutput.vi (under Operate Menu).
  
  
• Run Lambda.vi to read the graph of measured data (from PMOSoutput.vi) and to plot the measured data from the active region. The VI obtains K_p and λ_p from these data, for each of the voltage sweeps. Note that Lambda varies. Compare the average Lambda value with that from PMOSparam.vi.
  
  
• Click on Call PlotID_VSD.vi Green to bring up a plot of the active-region equation plot for –1/λ_p < V_SD < V_SDmax, compared with the measured data. Lambda.vi will be used in the Mathcad analysis file.
