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