Abstract
This paper presents a gyroscope interface architecture that
combines readout and self-calibration functions in a reconfigurable
fashion. The phase readout and calibration operation relies on the
phase shifts observed at the gyroscope outputs with respect to the
applied excitations. The proposed electrostatic calibration obviates
the use of any additional moving parts or calibration stage. The
significance of this work is having shared interface electronics
between the readout and calibration configurations, which
inherently compensates for the sources of drift in the electronics,
resulting in improved calibration accuracy. Experimental data is
presented that supports the theoretical analysis
of the proposed readout and self-calibration schemes.
