Title: noise analysis
Post by Won on Feb 16^th, 2005, 3:33pm

Hi,

I'm trying to do noise analysis in cadence.
I'm not sure I'm right.
In my circuit, there are several switches with two clocks (of course, no overlapping) like sampling hold circuit and input signal is just DC.
I'd like to see my input referred noise of my circuit
But I can't do AC analyis because in AC analysis switches are just off.
So, should I use the Pnoise or PXF?

Best regards

Won
