This paper presents a new, digital silicon MEMS gyroscope, which consists of micro-sensor, signal processing circuit
and micro-processor (MSC1214). The gyroscope structure allows it to achieve rolling rate, yaw angular rate and pitch
angular rate of rotating carrier. That is, it can detect the attitude of a rotating carrier. The key techniques of MEMS
gyroscope, including sensing construct, sensing principle, signal processing circuit design and test results are presented.
The test results show that the non-linearity of the gyroscope is less than 0.5% and sensitivity of the gyroscope is 0.01°/s
at atmospheric pressure, measuring range of yaw (or pitch) angular rate and rolling rate of rotating carrier is from -500 °
/s to +500 °/s and 0 Hz to 40 Hz, respectively.
