Patent ID: 7336937

Claim:
A method comprising: determining an amount of a direct-current offset present at a selected end point in a receiving path of a receiver, in which receiving path at least one gain factor is adjustable by a gain control, and setting a compensation quantity accordingly; exclusively in the case of a forthcoming adjustment of said at least one gain factor by said gain control, scaling said compensation quantity with a scaling factor to prevent a direct-current step at said selected end point due to said forthcoming adjustment of said at least one gain factor; and feeding said compensation quantity at a selected summing node into said receiving path to compensate for a direct-current offset coupled into said receiving path, wherein said direct-current offset comprises at least a first contribution and a second contribution, said first contribution being multiplied on said receiving path at least by a first adjustable gain factor and said second contribution being multiplied on said receiving path by a second adjustable gain factor, wherein said first contribution and said second contribution are estimated, and wherein said scaling factor is determined based on said estimated first contribution, said estimated second contribution and said forthcoming adjustment of said at least one gain factor.
