This research is devoted to the design of a digital excitation channel for a ring micromechanical gyroscope. The main methods of excitation of oscillations in angular rate vibration sensors were considered. The possibility of using a self-oscillating mode of operation for a ring resonator has been demonstrated. A mathematical model of operation of such system was created for this purpose. Besides a prototype electronics was built. It has experimentally confirmed the operability of the digital oscillation excitation channel and the possibility of stable maintenance of the oscillation velocity amplitude.
