Abstract
A MEMS gyroscope system and method for increasing a dynamic range of the MEMS gyroscope is provided. By adjusting a scale factor of the MEMS gyroscope, the highest sensed rate will be increased, which increases the dynamic range. The scale factor may be adjusted by using a variable sense bias and/or an automatic gain control loop in sense electronics.
