Title: About GBW of common mode feedback
Post by kidhyun on Apr 20^th, 2010, 4:21pm

Dear All,

I got a question.
I have an amplifier which is used in switched capacitor integrator.
If the common mode feedback GBW gets close to the differential GBW, is there any problem?
It seems that normally people use much less GBW for the common mode feedback than the differential mode GBW of the amplifier.

Thanks
