The invention discloses a circuit for reducing the offset of a bridge type sensor. According to the circuit, two groups of resistors are arranged in an ADC, and the two groups of resistors are connected to an input terminal of the bridge type sensor so that the influence of Voffset is reduced. According to the circuit, an output measuring circuit of the bridge type sensor is improved, two output voltages of the sensor can be adjusted, the voltage different between the two output voltages of the bridge type sensor is eliminated, and Voffset is eliminated.
