Title: Time base comprising an integrated micromechanical ring resonator
IPC: G04G3/00
Filed: 2000-11-01
Abstract: There is described a time base comprising a resonator (4) and an integrated electronic circuit (3) for driving the resonator into oscillation and for producing, in response to the oscillation, a signal having a determined frequency. The resonator is an integrated micromechanical ring resonator supported above a substrate (2) and adapted to oscillate, according to a first oscillation mode, around an axis of rotation (O) substantially perpendicular to the substrate, the ring resonator comprising a central post (5) extending from the substrate along the axis of rotation, a free-standing oscillating structure (6) connected to the central post and including an outer ring (60) coaxial with the axis of rotation and connected to the central post by means of a plurality of spring elements (62), and electrode structures (9; 9*) disposed around the outer ring and connected to the integrated electronic circuit. Electrodes (100, 120; 130, 150) are positioned under the free-standing oscillating structure in such a way as to drive and sense a second oscillation mode in a plane substantially perpendicular to the substrate and having a resonant frequency which is different from the resonant frequency of the first oscillation mode, a frequency difference between the resonant frequencies of both oscillation modes being used for compensating for the effect of temperature on the frequency of the signal produced by the time base. <IMAGE> <IMAGE>
