In this paper, an equivalent electrical analogue of the micromachined gyroscope driven by carrier is derived from dynamic and electronical characters of the gyroscope. The function of equivalent electrical analogue is verified by using electrical simulation tool-Pspice. The simulation and test results show that the equivalent electrical analogue of the micromachined gyroscope can replace the dynamic model and be used to design and simulate the interface circuits of the gyroscope. The circuits basing on the equivalent electrical analogue can touch the performance stand of the gyroscope.
