Comparison with the Generic Budget AnalysisFunctions In addition to using the Budget controller in ADS analog/RF schematics, ADS also offersbuilt-in RF budget MeasEqn function capability. Here are points that compare these twobudget analysis approaches:Using the Budget controller is in addition to and does not replace the built-in RFbudget MeasEqn function capability.The Budget controller is separate from and does not rely on the built-in budgetMeasEqn function items.

The key advantages of the Budget controller over budget analysis functions are:Much easier to use.Provides many more built-in budget measurements that you can select.Provides improved budget noise measurements.Supports tuning, sweeps, optimization, yield, etc.Supports AGC loops.Supports selection between alternate budget paths.Supports export of results in ASCII files for use in third-party tools, including Excel. The advantages of built-in RF budget MeasEqn function capability are:Supports flexible circuit topologies.Supports more flexible path selection.Supports user-defined subnetworks with frequency conversion.Supports more general mixer models.Supports concurrent simulation with other analog/RF analyses.
