It is for an analog output. I dont have the complete specs yets but I am sure the output impedance of the driver stage (invertor) is going to have high enough output impedance and that would create issues in stabilizing (since it will be a pole at lower freq. thought it is not the dominant pole) the amplifier (gain stage + invertor output stage). So, trying to see what options i have in terms of lowering the output impedance of this invertor to move the pole to a higher freq. I could use miller compensation but that would move the dominat pole to lower freq. which i am trying to avoid because of bw requirements.
