We aim to design electrostatic vibrating gyroscopes by using an electrical equivalent circuit analysis. Electrostatic MEMS devices are constructed from mechanical structure, electrical circuit and electromechanical transducers. The equivalent circuit represents whole systems as circuits and analyze them together. Therefore it is useful for designing MEMS. In our former research, we built the equivalent circuit model of the electrostatic comb transducer which is independent from external parameters like spring constants and controlled voltages. In this research, the proposed model was applied to the actual gyroscope and the analysis is agreed well to measurement results. As a result, we showed that the model was able to analyze the electromechanical coupled systems.
