System and method for the highly precise calibration of the sensor to variations in offset and sensitivity due to temperature

摘要

(57) the digital compensation circuit for calibrating a sensor SUMMARY is described. A communication circuit sequentially for receiving data relating to a plurality of parameters, is coupled to the communication circuit sequentially, the compensation circuit comprises means for providing a linear compensation as viewed from the portion of each temperature coefficient (TC). The means for providing a linear compensation as viewed from each portion and further detector means for providing an output by detecting a threshold value for the digital temperature, add in a plurality of registers coupled to the communication circuit sequentially and the detector circuit Te, digital temperature to provide a first value larger than the threshold value, is the second of a plurality of registers, the first of several registers plurality, when the digital temperature is less than the threshold value I and a register of the plurality that provides the value of the second. Furthermore, means for providing a linear compensation as viewed from each part, depending on the output of the detector means to be coupled to a plurality of registers and detector means to provide a linear compensation as viewed from a respective portion of the temperature coefficient I include a selector means for selecting one of the second one and the first one of the plurality of registers Te.
