Custom reconfigurable architecture for autonomous fault-recovery of MEMS vibratory sensor electronics

This paper presents a novel custom-reconfigurable architecture, which is tailored to accomplish the electronic circuits associated with MEMS vibratory sensors. The paradigm of this research work focuses on the JPL/Boeing gyroscope. Since the type of the sensor is vibratory, its dynamics are sensitive to temperature variation. In addition to this, the electronics associated with it, must be tolerable to operational deviations due to radiation. Therefore, our scope is to embed the two compensation loops of the gyro within an efficient adaptive platform able to compensate for the high range of gyro´s dynamics and radiation tolerance zone. In this paper we demonstrate the capability of our architecture to cope with permanent faults, which occur on the gyro electronics.
