Hello Tony. Thank you for your suggestion. I don't care how you bring this deficiency to the developers. I hope that the developers will make a slight modification - add points to the table function.

OK, thanks!

To test the models it is necessary to build a test pattern. I did so, selecting the parameters responsible for noise. There are other, improved models in my library. I will make new models, as it came

Just placed fet_noise.zip into the temp directory.

the ltspice has a poor math×programming support ... i doubt one can achieve a good conversion/function for a shot noise from the white() (using a channel input from WAV would be more realistic and pai

Wow! You could be my straight man. See the file Linear Congruential PRN Generator.zip in the temp directory for a pseudo-random source. Every time you put a clock pulse into it you get a different pse

Hello. The thread about correlated noise sources leads me to post a sub-circuit and symbol that computes random numbers based on the linear congruential generator algorithm: Z_new = (A x Z + C) mod M.

Hello Andy Well I had forgotten about flat(), but seeing it triggered the right memory.

You want to sweep the input voltage level and plot the THD at the output? You can't do that directly, but you can do it with your own 'add-in, which is a notch filter for 1 kHz. LTspice allows you to

One way to handle an EMI simulation, is to first construct a model representing how the signals couple from the aggressor to the victim, then simulate with that model. LTspice can help with the second
