Nonlinear Analysis Using 1-Tone Harmonic Balance with Harmonic Distortion and Spectrum as Measurements

Description

This simulation setup performs a yield analysis based on a 1-tone harmonic balance analysis of the amplifier. The measurements are total harmonic distortion and spectrum. When the simulation is complete the estimated yield is given, and the data is ready to be analyzed using the appropriate data displays.

Needed to Use Schematic

An amplifier schematic using nonlinear models must be inserted into the schematic. A sample schematic, Sample_Stat_PA, is initially present, inserted into the simulation schematic.

Main Schematic Settings

• Follow all the numbered steps in the upper left-hand box on this statistical analysis schematic
• Using the same parameters you initially used with the Power Amplifier DesignGuide, set the input frequency and available source power
  

Data Display Options

There are 3 data displays associated with this schematic:

• Four YSH's with Harmonic Distortion and Spectrum as the Measurements (YSH_1Tone_HD_Spect.dds)
  • The measurements included are total harmonic distortion, the magnitude in dB of the first, second and third harmonics of the output
  • The parameters Var1, Var2, Var3, and Var4 can be changed to any statistical component and the YSH will be immediately updated.
  • The yield specifications can be changed and the YSH will be immediately updated
  • The overall yield as well as the yield to each of the measurements are displayed
• Two MH's with Total Harmonic Distortion and the Magnitude of the First Harmonic at the Output as the Measurements (MH_1Tone_HD_Spect.dds)
  • The measurements that are graphed are total harmonic distortion and the magnitude of the first harmonic at the output
  • The vertical axis on each graph is number of occurrences
  • The number of pass, number of fail and overall yield are given
• SRP with Output Spectrum as the Measurement (SRP_1Tone_HD_Spect.dds)
  • The statistical response of the first through fifth harmonics at the output are graphed
  • The mean, the standard deviation, the mean plus one standard deviation and the mean minus one standard deviation are given in chart form for total harmonic distortion and the magnitude of the first harmonic in dB
    where YSH is Yield Sensitivity Histogram, MH is Measurement Histogram and SRP is Statistical Response Plot.
