An electronic device is provided, which includes a current supplying stage which is adapted to supply a first compensation current and a second compensation current to a first wire or a second wire, wherein the first compensation current is determined during a first clock period, when the first wire and the second wire are connected. The second compensation current is determined during a second clock period while the first wire and the second wire are not connected and the magnitude of the second current represents a ratio of a resistance value of the first wire and a resistance value of the second wire.
