The design principles of a mass-produced surface micromachined gyroscope are described. The device is integrated on a single 3 nun x 3 nun chip with a 3-mum BiCMOS process. It has a 4-mum-thick polysilicon structure, 5-V 6-mA supply, 12.5-mV/degrees/s sensitivity, 10 000 : 1 dynamic range, 30 000-gee shock survival, and -55 degreesC to +85 degreesC operating temperature.
