摘要

本文讨论了利萨焦氏调频陀螺仪振荡器中幅度增益控制(AGC)回路的特殊需求。在比较了可能的实现之后，公开了一种新的双模式架构，可以同时实现快速启动，并且不会对预期的证明质量轨迹产生相关畸变。在集成50 khz调频陀螺仪上的实验结果证实，启动时间约为100 ms，控制误差最小，无任何噪声恶化。

On amplitude-gain-control optimization for Lissajous frequency modulated MEMS gyroscopes

This work discusses the peculiar needs of amplitude-gain-control (AGC) loops in oscillators for Lissajous frequency modulated gyroscopes. After comparing possible implementations, a novel dual-mode architecture is disclosed, to simultaneously enable a fast start-up and no relevant distortion of the intended proof mass trajectory. Experimental results on an integrated 50-kHz frequency-modulated gyroscope confirm a start-up time of about 100 ms, with minimized control errors and without any noise worsening.
