Questions about unity-gain configuration.

[holddreams]

For a single ended opamp,the unity-gain configuration is the output connects the negative input .Using such configurationg ,we can simulate psrr,cmrr,and so on .

My question is ,
for differential output opamp,how to connect the circuit in order to form the unity-gain configuration?And how to simulate psrr,cmrr……?


Anyone can draw it?

Thanks.

look in to this doc..it suggests some test benches for charac. diff. circuits
