Abstract
An apparatus for optimizing a Wheatstone bridge robust in a temperature change, the apparatus including; a voltage difference measuring unit which measures a voltage difference between a current input end and a current output end of the Wheatstone bridge, wherein the Wheatstone bridge comprises a first resistor, a second resistor, a third resistor and a fourth resistor and a tuning resistor; and a resistance tuning controller which detects a resistance ratio of a first distribution resistance and a second distribution resistance of the tuning resistor so that the voltage difference measuring unit measures a maximum voltage difference, and controls tuning of the tuning resistor according to the detected resistance ratio.
