- The open-loop detection of Silicon micro-gyroscope always has a low bandwidth and a small dynamic range, and is sensitive with manufacturing errors. So this paper has studied the application of sigma-delta modulator in the closed-loop detection circuit of silicon gyroscope, and has put forward a preliminary hardware solution. Finally get a model of closed-loop detection system for gyro which can reach a signal-to-noise ratio index to 108.5 db, meeting the initial design specifications: resolution of 0.001 ø / s and range of ±200 ø / s. And in the aspect of hardware circuit, we have finished the interface circuit, including pre-amplifier circuit, the AD conversion module and the feedback module.
