Abstract
A method and circuit for preventing an output signal, which has been corrected through digital correction or analog correction, from deviating from a target value and for preventing power supply noise and power consumption from increasing. A sensor amplification circuit receives output of a sensor as an input signal. Correction points are set at predetermined temperature intervals. The sensor amplification circuit performs digital correction for correcting the input signal with correction data set for each correction point. Further, the sensor amplification circuit performs a second correction for correcting the input signal between the correction points with gradient data calculated from the correction data for two of the correction points that are adjacent to each other.
