A method for reducing errors in a tuning fork gyroscope includes determining a first distance, g, between an upper sense plate and a proof mass and a second distance, g, between a lower sense plate and the proof mass. The method further includes applying a first voltage, V, to the upper sense plate and a second voltage, V, to the lower sense plate, wherein the ratio of the first voltage and the second voltage is a function of the first distance and the second distance.

Method for fabricating a tuning fork gyroscope

An integrated sensor and electronics package wherein a micro-electromechanical sensor die is bonded to one side of the package substrate, one or more electronic chips are bonded to an opposite side of the package substrate, internal electrical connections run from the sensor die, through the package substrate, and to the one or more electronic chips, and input/output connections on the package substrate are electrically connected to one or more of the electronic chips.

Integrated sensor and electronics package

A tuning fork gyroscope typically including at least one proof mass with an upper sense plate disposed above the proof mass and a lower sense plate disposed below the proof mass and means for sensing changes in the nominal gaps between the sense plate and the proof mass and for outputting a signal indicative of the gyroscope angular rate.
