The intrinsic of non-linearity output and temperature drift for resistance sensor has a strong impact to the entire system accuracy and seriously limited its application. Due to the disadvantages of area, power and weight of conventional solution. Base on the compensation research of the resistance sensor, a sensor signal conditioner chip has been designed and implemented and further more the compensation algorithm has been investigated and finally integrated into the user software. The measurement shows that, a good linearity performance of output versus the measured pleasur
