Hi dear all friends
I used of folded cascade Unity-gain Buffer as depicted in the attached pic(open loop gain is greater than 800). I have an input voltage that varies between 250mV and 750mV. As you can see only around 450mV of input voltage, output able to track input. I need a buffer that be able to track input with offset below than 0.5mV and this variation that depicted in attached pic(that depends on input) is not reasonable for me.
I would be appreciated for any suggestion.
