Document Type and Number:
Japanese Patent JP3415631
Kind Code:
B2
Abstract:
A digital compensation circuit for calibrating a sensor is described. The compensator circuit includes a serial communication circuit for receiving data relating to a plurality of parameters and a compensation circuit coupled to serial communication circuit for providing piece-wise linear compensation of a temperature coefficient (TC). In one embodiment, the compensation circuit further includes a detector for detecting a threshold for a digital temperature and providing an output and a plurality of registers coupled to the detector and the serial communication circuit, a first plurality of registers for providing a first value if the digital temperature is above the threshold, a second of the plurality of registers for providing a second value if the digital temperature is below the threshold. The compensation circuit further includes a selector coupled to the detector and the plurality of registers for selecting one of the first and second of the plurality of registers dependent upon the output of the detector for providing piece-wise linear compensation of a temperature coefficient.
