发明名称 Apparatus and Method for Calibrating MEMS Inertial Sensors
摘要 The transduction scale factor for a MEMS gyroscope is calibrated without moving the MEMS device based on measurements of the resonator resonance frequency and the accelerometer resonance frequency as well as a distance value that may be a fixed distance value or a measured distance value. The measured distance value may be obtained by measuring the quality factor of the resonator or accelerometer and deriving the measured distance value from the quality factor measurement.
