Hello,

In reference to WBahn's blog at #(33) can we express:

Vout = Ad(Vd +/- Vcm/CMRR)

as to express a certain margin of error just as they have done at the bottom of this link:

http://en.wikipedia.org/wiki/Common-mode_rejection_ratio

I know they did that for an open loop gain but I see the formulas are similar?

thanks all for help

 

ooooppss
