Abstract
A device for controlling the frequency of resonance of an oscillating micro-electromechanical system includes: a microstructure, having a first body and a second body, which is capacitively coupled to the first body and elastically oscillatable with respect thereto at a calibratable frequency of resonance, a relative displacement between the second body and the first body being detectable from outside; and an amplifier coupled to the microstructure for detecting the relative displacement. DC decoupling elements are arranged between the amplifier and the microstructure.
