Title: How to analyze mismatch effect
Post by Roger on Jun 29^th, 2004, 6:41pm

Hi all,
Is there any good reference methodology to verify mismatch effect of any differential pair ?
The verification includes:
1.Identifying the most mismatch sensitive differential pairs
2.Verifying the improvement after redesign

I've checked some paper on IEEE. However, those are based on the Monte-Carlo simulation which is very time-consuming and difficult to verify the two items I listed.

Thanks.
Roger

Spectre 5.0 has a dcmatch analysis that seems to do exactly what you want without using Monte-Carlo simulation. For details see the Spectre Circuit Simulator User Guide.
