Abstract :
This paper presents improvements in recently developed distortion contribution analysis based on Volterra analysis on top of harmonic balance. The polynomial fitting is enhanced by perturbed source-wise fitting that breaks the input-output correlation of multi-input nonlinear sources. The contribution analysis is enhanced by a more effective frequency-domain convolution calculation, and possibility to track individual mixing products in mixer applications.
