Abstract:
1. A sensor device, comprising: an integrated circuit device; a transducer coupled to the integrated circuit device and configured to generate a transducer output; a first stress sensor coupled to the transducer or the integrated circuit device and configured to detect a first measure of stress being experienced by the sensor device, the first measure of stress being indicated by a first stress signal; and a compensation circuit coupled to the transducer and to the first stress sensor, the compensation circuit being configured to receive the transducer output and the first stress signal, calculate an amount of offset to at least partially compensate for the detected first measure of stress, and to adjust the transducer output in response to the first stress signal, wherein the adjusting is independent of operation of the transducer, and wherein the adjusting comprises adjusting the transducer output with the calculated amount of offset to generate a corrected output for the sensor device that compensates for the detected first measure of stress.
