MOS Amp Mismatch: Analyzing Effects & Comparing Dominance

[Questions999]

This is not a homework question,so please don't yell at me..

There is a question on my textbook..Analyze in a detailed manner the effects of the mismatch in the differential amplifier MOS.Which one has a dominating effect according to you and why?

I know how to analyze the effects of the transconductance and resistance mismatch ,but which one of them has a dominating effect and why?

I don't know how to compare these two?

Can you show us a typical MOS differential amp stage? And how would you model that stage? What are the candidates for effects that cause mismatches?
