ABSTRACT:
A semiconductor physical quantity sensing device to perform electrical trimming at low cost by using a CMOS manufacturing process and a small number of terminals. The semiconductor physical quantity sensing device includes a wheatstone bridge circuit, which is a sensor element, an auxiliary memory circuit, which stores provisional trimming data, a main memory circuit, which stores finalized trimming data, an adjusting circuit, which adjusts the output characteristics of the sensor element based on trimming data stored in the auxiliary memory circuit or the main memory circuit, with the elements and circuits being only configured of active elements and passive elements manufactured by way of the CMOS manufacturing process formed on a same semiconductor chip.
