Abstract:
1. A resonator comprising: a resonator body coupled to a connecting arm to form a combined mass; a plurality of actuation electrodes for driving the resonator into a first resonant mode in a first plane, in which the combined mass vibrates parallel to a first axis in the first plane, and also driving the resonator into a second resonant mode not in the first plane; and a detection arrangement for detecting the vibration in the first axis direction and generating an electrical output signal derived from the vibration, wherein the resonator further comprises a first anchor arrangement at which the resonator is fixed in position, wherein the first anchor arrangement connects to the resonator body at a first nodal point of the first resonant mode, and wherein the resonator further comprises a second anchor arrangement, and wherein the connecting arm includes a first end coupled to the second anchor arrangement at a second nodal point of the first resonant mode, wherein the connecting arm includes a second end coupled to the resonator body at a non-nodal point; and wherein the second nodal point of the first resonant mode is also a non-nodal point of the second resonant mode.
