A high-performance interface ASIC for quartz vibrating gyroscope

In this work, an interface ASIC for quartz vibrating gyroscope is presented. Its area is 5×4.4mm². Compared with traditional interface constructed by separate devices, such interface implemented with integrated circuits is advantageous in size and power consumption. This satisfies the requirements of miniature and low power consumption in space industry and military domain. The test results show that the entire system presents high performance in short term bias stability, nonlinearity, output noise, bias variation over temperature, and power consumption.
