Linear Analysis Using S-Parameters, Group Delay and Noise Figure as Measurements

Description

This simulation setup performs a yield analysis using the amplifier's small signal S-parameters, group delay and noise figure as measurements. Specifically S11, S22 and S21 are the S-parameters used. 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 linear or 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 Amplifier DesignGuide, set the frequency sweep range.

Data Display Outputs

There are 2 data displays associated with this schematic:

• One YSH With S-Parameters, Group Delay and Noise Figure as the Measurements (YSH_SParams_GrpDly_NF_One.dds)
  • The S-Parameters included are S11, S21, and S22 as well as group delay and noise figure
  • The parameter to be graphed, Var1, can be changed and the YSH will be immediately updated
  • The yield specifications can be changed and the YSH will be immediately updated
  • The frequency range over which the yield specifications are applied can be changed and the YSH will be immediately updated
  • The overall yield, as well as the yield for S11, S22, S21, group delay and noise figure are displayed
  • The number of amplifiers showing unconditional stability is displayed
• Four YSH's With S-Parameters, Group Delay and Noise Figure as the Measurements (YSH_Sparams_GrpDly_NF_Four.dds)
  • All the same features as above except there are four YSH's plotted, with one assignable circuit parameter for each YSH
    where YSH is Yield Sensitivity Histogram.
