    how to separate a noise contributor in pnoise analysis? Reply

    HI folks,

      

    My question is:

    in pnoise simulation, can I activate/deactivate specific voltage sources or instances as only noise contributor?

     

    For example, in transient noise analysis, Virtuoso provdes a feature, 'Noise Contribution On/Off'' with a given instance list. I am looking for similar feature in pnoise analysis.

     

    Virtuoso verion of mine is IC6.1.5-64b.500.12

     

    I appreciate any comment from you.

    Jae Wook

    You don't need this feature in pnoise analysis because you can get the equivalent information much more easily from the Noise Summary (something that is not available for transient noise analysis).

    Hi Jae

    In ADE L go to Simulation-->Options-->Analog Then under Main tab, at the bottom of the page there is "NOISE OPTIONS" and there you can turn on and off the noise of different components.

     

    Good luck

     Dear Frank,

     

    Thanks for your comment.

     

    Yes, the Noise Summary is very helpful in figuring out the contribution of each noise source.

    But, the summary shows only numbers. I need to check the noise contributions in frequency domain, for which the summary cannot help at all (at least as far as I know).

     

    Best,

    Jae Wook
