pac analysis
Hi,
I am new in cadance, till now I have used only PSpice so sorry for may be stupid question. I make SD ADC so I am designing OP amp for the untegrator. I made AC analysis with continuos CMFB of the amp. In reality amp will operate with SC CMFB. From manuals of Spectre as I understood there is some PAC analysis which makes some thing like ordinary AC analysis but using real SC operating points. Is it real or is it wrong. So if it is real, are plots from this analysis look like those from ordinary AC analysis (gain versus frequency, andphase versus frequency).
Can any one post useful manual, how to run this analysis!
