ABSTRACT:
An error correction circuit compensates for baseline wander which can occur when a data signal is passed through a DC isolation stage. The data signal, and its inverse are compared with a common reference level, and the error signal modifies the charge on a capacitor which forms part of a pair of negative feedback loop to control the baseline level.
