Title: a question about rail-to-rail opamp
Post by icguy on Jun 29^th, 2008, 8:22am

is there certain ciucuit that can sense the output common mode signal for the cmfb? As most of the components can't sense the rail-to-rail output signal thank you :)!

try a resistive divider, or a switched-capacitor common mode sense circuit.
