I have been reading about "Zero impedance line outputs" where the output capacitor is in the feedback loop of an opamp by means of multiple resistive paths back to the non-inverting input.
The issue is that the stage seems necessarily need gain to function, how would one go about including the output capacitor and 50 ohm isolating resistor in a non-inverting voltage follower?
Just take the feedback from the output side of the capacitor?
