Investigation on the Effect of Self-Clocking in MEMS Gyroscope

This paper investigates the mechanism of selfclocking in digital systems of MEMS gyroscopes, aiming to achieve stable phase-frequency characteristics by synchronizing the sampling rate with the input signal frequency. Experimental validations are performed to demonstrate the effectiveness of self-clocking in improving the temperature stability of gyroscopes. The results show that self-clocking indeed contributes to minimizing the bias drift with temperature variations, thereby improving the overall performance and reliability. Moreover, a comprehensive analysis of various self-clocking application scenarios is presented, including the principles of the self-clocking and the specific functions of each clock. These findings provide valuable insights for implementing self-clocking in digital MEMS gyroscope systems.
