Nonlinearity contribution analysis of large signal analysis
Apr 29th, 2024, 2:50am
 
I have been doing linear power amplifier design for sometime, and I am always wondering why there is no main-stream tool for nonlinearity contribution analysis (A vector plot of various distortion components stemming from different devices for a given IM product).
For LNA or mixer design, Noise contribution analysis is quite common since noise are uncorrelated and there is generally no noise cancelling occurring. For distortion analysis in HB, I understand that it is more straightforward to keep track of the total distortion for a given node than to separate them according to their origins.
I have seen some papers on Volterra-on-top-HB analysis, and I think it is possible to integrate this kind of analysis into main stream tools. Is the absence due to lack of perceived market demand? I think it would be well received for linear (power) amplifier designers.
