MICROELECTROMECHANICAL RATE SENSOR

摘要

A high signal to noise ratio circuit and signal processing scheme described herein provides signal power above a noise floor such that high performance rate gyro operation can be achieved. The technology described herein exploits the combination of very low noise rate signal front end and a carrier frequency locked to a crystal filter's passband. A fixed single frequency and a sampled alternating current amplitude for conveyance of rate information is utilized.
