Zusammenfassung:	A system includes: a first device; and a second device coupled to the first device. The second device has a receiver. The receiver has a comparator and a controller. The comparator has an adjustment terminal. The controller has an input and an output. The output of the controller is coupled to the adjustment terminal of the comparator. The controller is configured to: obtain an offset estimation model; receive an input voltage at its input; determine a comparator offset responsive to the offset estimation model and the input voltage; and provide an adjustment control signal to its output responsive to the determined comparator offset.
