Abstract

A design of digital application specific integrated circuit (ASIC) of quartz-gyro is proposed in this paper. The digital drive circuit with fast-start oscillation and digital detection circuit with low noise are adopted to implement the digital output of the main circuit node and high precision angular velocity detection. The interface circuit is fabricated in a standard 0.35 μm CMOS technology and test result shows the angular random walk and zero stability are 0.022°/h and 2.9°/h (1σ), respectively. The bias-instability is 1°/h (Allen). The nonlinearity is limited to 0.035% and the zero temperature drift is 16°/h from-45°C to 85°C. The chip exhibits great superiority on the aspects of high precision angular velocity digital detection and temperature characteristics of overall system.
