Abstract
A method of compensating a direct-current offset coupled into a receiving path of a receiver, the receiving path having at least one gain factor adjustable by a gain control, which method first determines an amount of a direct-current offset present at a selected end point in the receiving path. A compensation quantity is set accordingly. In case of a forthcoming adjustment of the at least one gain factor by the gain control, the compensation quantity is then scaled with a scaling factor to prevent a direct-current step at the selected end point due to this forthcoming adjustment. The final compensation quantity is fed at a selected summing node into the receiving path. The invention is also directed to a corresponding receiver, an electronic device comprising such a receiver, a hardware component for such a receiver and to a corresponding software program product.
