stability of a fully differential amplifier

[artho]

Hi,

I would like to know how i can check the stability of a fully differential amplifier (with CMFB).

Thanks.

What stability are you concerned about, (DC offset, gain, frequency response, etc.)?

 

[artho]

I can check the stability as a whole or i have to analyze parameter by parameter?
Thank you.

Thank you.

You need to test for each parameter individually.

thanks for your answer crustchow.
So how do i test for each one of these (gain, slew rate, offset, etc) ?
Thank you.
