Abstract
Example embodiments of the disclosed technology methods, devices, and systems for compensating a sensor having thermal gradients. In one embodiment, a system is provided that includes a sensor, including a first half-bridge transducer configured to output a first pressure signal associated with a first received pressure; a first set of span resistors coupled to the first half-bridge transducer, and configured generate a first compensated pressure signal; a second half-bridge transducer, configured to output a second pressure signal associated with a second received pressure; and a second set of span resistors coupled to the second half-bridge transducer and configured to generate a second compensated pressure signal. The system includes an output port that is configured to output a signal associated with a difference between the first compensated pressure signal and the second compensated pressure signal.
