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

Description

This simulation setup performs a yield optimization using the amplifier's small signal S-parameters, group delay and noise figure as measurements. Specifically S11, S22 and S21 are the S-parameter measurements.

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 optimization schematic
• Using the same parameters you initially used with the Amplifier DesignGuide, set the input frequency range
  

Data Display Options

This DesignGuide does not include data displays prepared to directly plot the yield optimization results. However, when the optimization is complete a rough estimated yield is given. To plot results after the yield optimization, from the menu select Simulate , then Update Optimization Values . This fixes the new optimized parameters on the amplifier schematic. Then a yield analysis can be simulated, using the new optimum parameters.
