Title:
CONTINUOUS MONITORING OF GYROSCOPE SENSOR FORCED-TO-REBALANCE LOOP ELECTRONICS
Document Type and Number:
WIPO Patent Application WO/2024/042779
Kind Code:
A1
Abstract:
A gyro sensor circuit includes a gyro sensor generating an RF sensing signal according to an angular movement, an RF sense path configured to receive and process the RF sensing signal. The RF sense path comprises a first chopper configured to chop the RF signal at a first chopping frequency to generate a chopped signal, and a demodulator configured to mix the chopped signal with an LO signal to output a baseband signal. The circuit further includes a feedback loop comprising a chopper re-modulator configured to chop and modulate the baseband signal at a frequency of the LO signal, a first amplifier configured to amplify the modulated feedback signal, and a test voltage monitor configured to extract a component corresponding to the LO signal from the modulated feedback signal, and compare a voltage of the extracted component with an expected value determined based on a gain of the first amplifier.
