Compact conversion and cyclostationary noise modeling of pn-junction diodes in low-injection. Part II. Discussion

Starting from the compact conversion and cyclostationary p-n diode noise model presented in the companion paper , we present an extensive validation based on comparisons with physics-based numerical simulations. Furthermore, we discuss the validity of two widely exploited system-oriented cyclostationary noise modeling approaches, based on the modulation of small-signal stationary noise spectra. We demonstrate that care must be exerted in the choice of the modulation scheme, unless the intrinsic diode noise is purely white, in which case a simple modulated shot noise approach can provide, with proper inclusion of parasitics, satisfactorily accurate results.
