Method for compensating for quadrature
Abstract:
A method for compensating for the quadrature of a micromechanical structure, the micromechanical structure having a substrate having a main extension plane, a seismic mass that is attached by spring elements to the substrate, and first and second compensation electrodes anchored to the substrate; in response to application of a first quadrature voltage between the first compensation electrode and the seismic mass, a first compensation force being produced on the seismic mass and, in response to application of a second quadrature voltage between the second compensation electrode and the seismic mass, a second compensation force being produced on the seismic mass and, in addition, the second quadrature voltage being adjusted as a function of the first quadrature voltage.
