摘要:
A MEMS device comprises a proof mass suspended above a substrate, one or more driving combs, and one or more sensing combs. During operation, a DC actuating potential in series with an AC modulation potential is applied to the proof mass, and an AC actuating potential is applied to the one or more driving combs such that the proof mass moves in an oscillatory manner. An inertial sensing system further comprises a sensing element configured to detect a rotation information coupled with an AC signal and an acceleration information coupled with a DC signal.
摘要(中):
MEMS器件包括悬浮在衬底上的校准块,一个或多个驱动梳和一个或多个感测梳。 在操作期间,将与AC调制电位串联的DC致动电位施加到检测质量块,并且将AC致动电位施加到一个或多个驱动梳,使得校准质量块以振荡方式移动。 惯性感测系统还包括感测元件,其被配置为检测与AC信号耦合的旋转信息和与DC信号耦合的加速度信息。
