Hello again. What is the criteria for choosing the value of the
correlation parameter value for matched transistors, when performing
Monte Carlo simulations in ADE?
For example, in the widely-known article "Recommended Spectre Monte
Carlo Modeling Methodology" (www.designers-guide.org/Modeling/
montecarlo.pdf), they use cc=0.75 for correlating two matched
resistors. What about the values for, lets say, matched transistors in
a differential pair or in a mirror? Does the correlation parameter
should be chosen depending if the transistors are multi-fingered and
interleaved? What about the cases of more than 2 transistors (for
instance, a current mirror with several copies)?
I suspect it might have something to do with the particular process
taken into account. I am using the AMS C35B4 cmos technology, but
unfortunately I haven't been able to find any suggestions for the
values of the correlation parameter that should be used...
Thanks a lot for any ideas!
Cheers,
Jorge.
