摘要: Systems and methods for improving MEMS gyroscope start time are provided. In one embodiment, a circuit board (105) for a MEMS gyroscope system (100) comprises: a proof mass assembly (110); a proof mass control loop (135) coupled to the proof mass assembly (110) by a first proof mass motion sensor pickup line (120) and a second proof mass motion sensor pickup line (122), where the proof mass control loop (135) generates a set of drive signals (140,142)that operate the proof mass assembly (110) using a first capacitive signal from the first proof mass motion sensor pickup line (120) and a second capacitive signal from the second proof mass motion sensor pickup line (122); and a tunable capacitive coupler (158, 158A) connected to at least one of the first or the second proof mass motion sensor pickup lines (120, 122), where the tunable capacitive coupler varies at least one of the first and second charge signals as a function of the drive signals (140,142).
