MEMS INERTIAL SENSOR DEVICE WITH DETERMINATION OF THE BIAS VALUE OF A GYROSCOPE THEROF AND CORRESPONDING METHOD

摘要

A MEMS inertial sensor device has a package and a gyroscopic sensor, an accelerometric sensor, and an ASIC electronic circuit integrated within the package. The ASIC is operatively coupled to the gyroscopic sensor and the accelerometric sensor for supplying at an output a gyroscopic signal indicative of an angular velocity and an acceleration signal indicative of an acceleration acting on the MEMS inertial sensor device. The ASIC is provided with a processing module, which may be of a purely hardware type, for processing jointly the gyroscopic signal and the accelerometric signal and determining a bias value present on the gyroscopic signal.
