The more I ask about the infamous correlation parameter, the more
astonished I get... Today I asked an associate professor, which I know
has some experience in analog design (i.e. has done some working
silicon), and he was totally surprised to learn about it... he had no
idea of its existence!!!
I have also searched in the do***entation of two other design kits
besides AMS (namely, TSMC & UMC), and found no references whatsoever
about how to take into account matched groups of transistors. I think
these are rather well-known and widely-used processes, why does it
seem nobody cared about do***enting the proper way of performing
montecarlo simulations, taking into account matched pairs?
....I guess virtually everybody working in analog MUST do montecarlo
simulations before going to fabrication, and MUST take into account
matching on those simulations... How do they (properly) do it? :O
Puzzled (and also desperate, but that's normal :-) ),
Jorge.
