Convergence problem in system level sim. of DCR
Aug 16^th, 2007, 12:41pm

Hi all,

I'm simulating a direct conversion receiver consists of LNA, Mixer, Pre AMp, LPF and Limiting Amp. I used PSS PXF PNoise to see overal gain and NF. However the PSS simulation does not converge. I was using Moderate as tolerance, I changed it to libarel and conservative but both gave same convergence problem. Can you please suggest what else I can do?

Thanks

It's hard to answer without more information... there are potentially ots of things that could cause convergence failure. Regards, Andrew.
