ABSTRACT:
A temperature dependent signal compensation signal for generating a dual sloped calibration signal is disclosed. The temperature compensation circuit may be coupled to an integrated transducer amplifier circuit that applies the compensation signal for reducing error generated by changing operating temperatures. The signal compensation circuit provides for independent adjustment of the slope of the dual sloped compensation signal in response to changes in the operating temperature of the signal compensation circuit. A technique for generating and adjusting the slope of the dual sloped compensation signal in response to the operating temperature exceeding and falling below a first operating temperature is also disclosed.
