Title: Re: Pnoise results do not seem correct Post by Andrew Beckett on Jan 8th, 2014, 5:25pm My suggestion would be to contact http://support.cadence.com because then an application engineer can take a look at the data and your circuit with you. It's pretty hard to tell what the issue is purely from the pictures you've provided, I'd have thought (it certainly doesn't look immediately obvious to me, although I didn't spend too long looking at it). If this is holding you up, that really would be my suggestion. You're probably paying for support as part of your contract, so best to use it! Regards, Andrew. |
Title: Re: Pnoise results do not seem correct Post by prestonee on Jan 9th, 2014, 6:29am That was attempted a wile back. We havent been impressed with our regional cadence rep when it comes to switch cap noise simulation. he seems to be more geared for rf and oscillator simulation type questions. But I will retry the attempt. thank you ps - A coworker in a different group/location told me that while noisetype=timedomain is intended for sampled systems, that if i run the output through an ideal S/H and run pnoise on that output that i can just use the noisetype=sources and pac sidebands of 0, since the S/H does the folding in its own transfer function. This also lets me use n()/pac() without having to transform the pac results. Have an opinion on this? |
