Novel neural approach for parameter extraction of microwave transistor noise models

摘要

A novel approach for parameter extraction of microwave transistor noise models based on artificial neural networks is proposed in this work. Neural networks are applied to determine parameters of the noise model directly from the measured noise and small-signal scattering parameters without any optimization procedure. Moreover, unlike the similar existing procedures, development of the extraction procedure does not require any measured data or optimizations in a circuit simulator, making the procedure more efficient, as described in detail in the paper. The approach has been applied to extraction of the Pospieszalski's noise model parameters for a specific pseudomorphic high-electron-mobility transistor (pHEMT) device working under different temperatures.
