Abstract :
In this paper, a mixed-signal interface for gyroscopes is designed, proving the feasibility of interface with PI controller-based self-oscillation and bandpass sigma delta modulator. According to the simulation results, driving circuit is stably self-excited and sensing circuit functions well as a sigma delta modulator.
