该论文提出了一种用于电子稳定控制（ESC）的三轴陀螺仪，通过增强现有子系统的功能实现了低开销的连续安全监测，确保MEMS和电路故障能被及时标记，避免误判为有效信号。解决了汽车安全系统中对高精度和连续自检的需求。
(ESC) systems [1], which are mandated for new vehicles in many countries. Gyroscopes for ESC applications require higher performance specifications than those of consumer gyroscopes available in the market today. In addition, they require continuous safety monitoring so that changes in the output, which happen in the field due to MEMS and circuit malfunctions, are flagged and are not misconstrued for legitimate signals. This work presents a low-overhead approach for implementing accurate continuous safety monitoring by augmenting the function of already existing sub-systems. In addition, the paper discusses circuit architecture and design techniques, which achieve the stringent ESC specifications for noise, robustness to parasitic resonant modes in the sensor element and offset drift due to temperature and Electro-Magnetic
