Abstract
A current sensing circuit includes a current sense amplifier and a correction circuit. The current sense amplifier has an offset voltage. The correction circuit is configured to evaluate the offset voltage of the current sense amplifier. The correction circuit is further configured to issue a correction signal to the current sense amplifier based upon the evaluated offset voltage. The correction signal is to adjust the offset voltage.
