To AC-Couple or Not to AC-Couple? That Is the Question!
The problem with a single, AC-coupling capacitor is that the signal is attenuated at frequencies below the pole frequency—the smaller the capacitor, the higher the pole frequency. SAG compensation boosts the low-frequency response in order to compensate for the low-frequency attenuation (Figure 5).
