Claim 18:
19. A method of controlling a microelectromechanical gyroscope that includes a support structure, a driving mass capacitively coupled to the support structure and movable relative to the support structure according to a driving axis and a microelectromechanical loop, having a resonance frequency and a loop gain and including the driving mass, the method comprising:
setting the microelectromechanical loop in oscillation;
sensing a position of the driving mass with respect to the support structure; and
maintaining a modulus of the loop gain at a unitary value at the resonance frequency;
wherein maintaining the modulus of the loop gain includes acquiring samples of loop signals indicative of a position of the driving mass with respect to the support structure and amplifying the samples in open loop, and wherein the acquiring and amplifying are temporally separate and not overlapped.
