Turn off 1/f noise in Transient Noise simulation

Jessica Wu over 4 years ago

Hi everyone,

I got a question here: how could I turn off the flicker(1/f) noise of a circuit in Transient Noise simulation?

Please let me know if you have any clue! Thanks a lot!

Best,

Jessica

Jessica,

On Simulation->Options->Analog, on the Main tab, scroll to the bottom, and set the Noise Contribution to off. Then below that set noiseoff_type to flicker. In the Instance List field you could select all the transistors, or probably just put "*" in the field. This should then just turn off the flicker noise for all devices.

Hi Andrew,

Thank you for your help! I didn't find "Noiseoff_type" when I scrolled down, just like the figure below shows. Is it because my cadence version is too old?

Thanks,

Presumably. The option has been available for a pretty long time though and unfortunately my ESP circuit is broken so I don’t know which versions (IC and SPECTRE) that you’re using.

Thank you! Then I think my cadence version is too old. Thanks again!
