Innovative angular sensor read-out multi-axes digital front-end chain

摘要

The invention relates to a controller, and more particularly, to systems, devices and methods of processing multiple sensor signals of a gyroscope. The signal processor includes: a front end amplifier for converting a signal into a voltage variation signal; at least one analog-to-digital converter coupled to the front end amplifier and operative to convert an analog signal into a digital signal; and at least one demodulator coupled to the analog-to-digital converter and operative to demodulate the digital signal to thereby extract an envelope signal therefrom.
