Apparatuses, methods, and systems for compensating baseline offset in a read channel of an analog storage device. The apparatus generally includes an AC-coupling circuit configured to transfer an analog signal from an analog storage device to the read channel, a configurable current device coupled to the AC-coupling circuit, comparator coupled to the AC-coupling circuit, and logic coupled to the configurable current device and the comparator, wherein the logic is adapted to configure said current device in response to an output of at least one of the AC-coupling circuit and the comparator. The method generally includes the steps of coupling an analog storage device and the read channel with an AC-coupling circuit, detecting a baseline or a component of an analog signal at a node downstream from the AC-coupling circuit, and configuring a current device to modify the analog signal in response to detecting the baseline or a component of the analog signal, wherein the current device is coupled to a node downstream from the AC-coupling circuit and upstream from a signal processor configured to operate on the analog signal.
