Abstract
Methods and systems for compensation of a microelectromechanical system (MEMS) sensor may include associating test temperature values with input test signal values, identifying temperature-input signal pairs, and applying one of the test temperature values and one of the test signal values to the MEMS sensor. Desired output signal values may be determined, with each of the desired output signal values corresponding to one of the applied temperature-input signal pairs. Measured output signal values from the MEMS sensor may be measured, with each of the measured output signal values corresponding to one of the applied temperature-input signal pairs. Compensation terms may be determined based on the plurality of temperature-input signal pairs, the corresponding plurality of measured output signal values, and the corresponding plurality of desired output signal values. Compensation terms may be used to modify a sense signal of the MEMS sensor.
