Key Points

Develop a statistical neuro-space mapping framework to capture large-signal performance variations across nonlinear microwave devices using minimal large-signal measurements.
Formulated a nominal device model utilizing direct current (DC), small-signal, and large-signal data.
Constructed neural networks trained on DC and small-signal data to create a nonlinear mapping between the nominal model and randomly sampled devices across a population.
Implemented a simultaneous training and statistical parameter extraction algorithm controlled by a compact set of statistical variables.
Demonstrated superior predictive accuracy over conventional linear mapping methods for both small and large statistical device variations.
Successfully validated the technique on microwave transistor benchmarks and statistical analyses of a two-stage amplifier while minimizing reliance on expensive large-signal data.
