SENSOR WITH METHOD TO CORRECT OFFSET DRIFT IN CYCLIC SIGNALS.

摘要

A method for correcting offset drift in a sensor used in cyclic sensing is provided. The method includes: identifying a target value for a parameter of a signal between sensing cycles of the sensor; ascertaining a difference between a measured value for the signal and the target value; ascertaining a duration between the sensing cycles; using the difference and the duration, calculating a number of steps to attain the target value from the measured value; and adjusting the measured value by the number of steps to substantially agree with the target value. A pressure sensor is disclosed.
