Abstract
This article reports a MEMS disk resonator gyroscope (DRG) with superior overall performance in terms of bias instability, measurement range, and size. Specifically, a fully filled electrodes MEMS DRG is proposed to improve sensing capacitance to 23.66 pF and drive capacitance to 6.14 pF. The DRG is fabricated using a wafer-level vacuum-package process and is controlled and sensed by a configurable ASIC, enabling a small footprint. The DRG achieves an angle random walk of 0.05°/√h and bias instability of 0.42°/h within a full scale of ±300°/s, making it a very promising solution for angular measurement in high-end industrial applications.
