摘要
A driving circuit for a gyroscope device provided with a micromechanical detection structure having a driving mass, which is driven in resonance condition and elastically coupled to which is a sensing mass for enabling detection of angular velocity; the driving circuit has: a set of driving electrodes, coupled to the driving mass; a driving stage supplying driving signals to the set of driving electrodes to cause oscillation in resonance condition of the driving mass; and a reading stage, which detects movement of the driving mass to implement a feedback control of the driving signals. In particular, the reading stage is selectively coupleable to the set of driving electrodes in a way temporally alternative to the driving stage, for discrete-time detection of the movement of the driving mass.
