Linear Optimization Using S-Parameters as Measurements

Description

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

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 Power Amplifier DesignGuide, set the input frequency range

  Note This is the simplest optimization schematic and is a good one to start out with.

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.
