Abstract:
1. A device for operating an oscillatable unit of a vibration resonator, comprising: feedback electronics; a piezodrive connected with the oscillatable unit, and said feedback electronics, said feedback electronics excites said piezodrive to oscillate by means of a periodic exciter signal having rising and falling edges, and a response signal of said piezodrive is fed back to said feedback electronics; and at least one peak compensation unit, which removes from the response signal at least one interference signal, which results from the charge-reversal process of the piezodrive; wherein: said at least one peak compensation unit has at least one amplifying unit which amplifies the response signal of said piezodrive, and whose amplification factor is controllable by the exciter signal of said feedback electronics in such a manner that the amplification factor is minimal during the rising and/or during the falling edges of the exciter signal.
