a jolly hello to all!
i've got a question about bandgap's TC and Vref.
is it true that there is a correlation between TC and Vref.
for example: you have 50 Monte Carlo runs, then you get 50 Vref values at 25 degress and 50 TC. now calculate the correlation coefficient between them.
Someone told me if you get a high correlation value, you've build a good bandgap,
and then it's possible to trim the bandgap, only if you measure the vref at one temperature.
is this true ? maybe someone can help
thx
