ABSTRACT:
The inertial sensor comprises a piezoelectric plate having a vibrator member defined therein carrying excitation electrodes connected to an excitation circuit including conductor tracks carried by the piezoelectric plate the excitation circuit including a disturbing circuit portion in which the excitation circuit has compensation branches associated with corresponding disturbing conductor track portions, each compensation branch having one end connected to the corresponding disturbing conductor track portion and extending on a side of the midplane that is opposite from the side on which the corresponding disturbing conductor track portion extends.
