DEVICE FOR PUTTING OSCILLATION UNIT OF VIBRATION RESONATOR IN ACTION (VERSIONS) Russian patent published in 2008 - IPC B06B1/02 H03B1/04 

FIELD: electronics.

SUBSTANCE: device has piezoelectric drive 2 connected with oscillation unit 1 and feedback electronic unit 3. Feedback electronic unit 3 excites oscillations of piezoelectric drive 2 by means of periodic exciting signal 20 characterizing by positive-going and negative-going slopes. Response signal 21 of piezoelectric drive returns to feedback electronic unit 3. At least one peak compensation unit 4 is provided, which unit suppresses at least one parasitic signal 2 in response signal 1, which parasitic signal arises during piezoelectric drive's 2 recharge processes. At least one suppress unit 5, 13 with at least one commutation member 6, 14 is provided in peak compensation unit 4. Suppress unit 5, 13 is controlled by exciting signal 20 of feedback electronic unit 3 in such a way that during positive-going or negative-going slopes in exciting signal 20, piezoelectric drive 2 is in conducting connection with mass.

EFFECT: damping of parasitic signal in response signal; reduced number of costly parts.
