Abstract
A data recovery circuit provides compensation for baseline wander exhibited by a data signal. An adaptive equalizer generates a recovered data signal from a data input. A level shifter and low-pass filter provide a compensation signal as a function of the recovered data signal. An adaptation engine adjusts the level of the compensation signal to compensate for baseline wander. The adaptive equalizer generates the recovered data signal as a function of the data input and the compensation signal, thereby providing accurate recovery of the data signal.
