Title: Noise
Post by safwatonline on Feb 14^th, 2008, 11:33am

Hello,
i am doing a SC design with a tough spec on noise using eldo, so i am currently using the transient noise of mentor and i was wondering of how accurate is it. (sadly i don't have access to spectre RF)
also i saw a thread here on the forum talking about using a "fracpole" to model the 1/f noise, Sorry but what is the fracpole!!
regards,
Safwat

I can safely say that the accuracy anywhere near as good as SpectreRF, but you should also be aware that there is a nasty tradeoff between speed and accuracy with transient noise. That is particularly true if you hope to include flicker noise. That is going to be one long simulation.

FracPole is a component that implements a fractional pole (or zero). It is described in some detail in several papers in the Modeling section of this site.
