A Configurable Measurement Range and Bandwidth Mems Disk Resonator Gyroscope

Abstract

This paper reports a closed-loop MEMS disk resonator gyroscope (DRG) with configurable measurement range and bandwidth. A configurable ASIC is employed for the measurement range and bandwidth configuration and the design methods of measurement range and bandwidth are studied. By changing the registers of the ASIC, the measurement range is configured from 450 to 2250°/s, and the bandwidth is configured from 10 to 100 Hz. Meanwhile, experiments prove that increasing the measurement range or bandwidth will deteriorate the accuracy of the gyroscope to some degree.
