hello,
in Razavi's book , i noted a fully diffrential amp. used in unity feedback configuration by just shorting the i/p to the output.
my question is when we are connecting the i/p to the o/p directly ,how the diffrential pair will affect them (i.e. we are shorting the diff pair)
i get it in making a bufer with diff. to single-ended where the o/p is connected to the inverting terminal and the i/p is connected to non-inverting terminal ,but in this case they are not shorted .
thnx for the help
