Is it possible to also save phase information for the gain transfer function in noise analysis?

NourSeif

Hi,


I was wondering if it is possible to get plots for the phase of the transfer function in noise analysis like in AC analysis without the need to run AC analysis.
It would be really helpful and save extra time in simulation time.

Kind regards,

Nour

  • Nour,

    No. You would need to run a separate xf analysis (that way you don't need to add an ac magnitude on the input source) with the output specified the same way as the noise analysis. Then on the Results->Direct Plot->Main Form you can pick the xf analysis, and click on the input source - having picked phase. With the xf analysis you get the complex transfer function. With noise analysis, you only get the magnitude (mostly this is because noise analysis is concerned with noise powers).

    Thank you, Andrew.
    I appreciate your fast and detailed answer.
