摘要: An MEMS gyroscope is disclosed, capable of computing the rotating angle of a DUT being attached thereto without the need to execute an off-line calibration process, of precluding the execution of an integration process, and of executing an on-line compensation process for the error introduced by the sensing circuit defect and by the mechanical structure defect of its gyroscope module. The disclosed MEMS gyroscope comprises: a gyroscope module, a sensing module coupled with the gyroscope module, and a control module couple with the gyroscope module and the sensing module, respectively. The control module receives the system dynamic of the gyroscope module sensed by the sensing module, and applies a gyroscope control method for controlling the gyroscope module and computing the rotating angle of the DUT. Moreover, the control module outputs a control signal including two extra frequency signals, to the gyroscope module, for driving the gyroscope module into operation.
