    Abstract: A circuit includes a Wheatstone bridge and a correction circuit operable to correct an output voltage offset of the Wheatstone bridge. The correction circuit includes a supply module configured to supply the Wheatstone bridge with a voltage and output a first current applied to the Wheatstone bridge and output a second current proportional to the first current. A digital/analog current converter outputs a correction current to the outputs of the Wheatstone bridge circuit in response to a digital correction signal and the second current.
