Study on the Circuit of Driving Loop Control for Micromachined Vibratory Gyroscope

LI Qian,LI Xiao-ying,CHANG Hong-long,JIANG Qing-hua (Micro/Nano System Laboratory, Northwestern Polytechnic University, Xi'an 710072 ,China)  
Based on the mechanical model of the MEMS vibratory gyroscope,the relationships between the driving signal and the gyro sensitivity are derived. It shows that in order to obtain a high sensitivity and low drift, the gyroscope must be working in resonance condition, and the amplitude of driving signal must be constant. For these considerations, a driving circuit with phase locked loop and constant amplitude loop is described. In resonance condition, the driving signal and the driving mode displacement signal are in phase-quadrature. Using this characteristic this paper adopts phase locked loop to adjust the frequency of the driving signal in accordance with the difference of the natural frequency in the driving mode. The constant amplitude loop utilizes half-wave rectification circuit and DC voltage adjustment circuit to keep the driving signal constant. The experiment shows that, with the phase locked loop and constant amplitude control, the driving circuit reduces the output noise, improves the gyro sensitivity and the stability of scale factor.
