CAPACITANCE-TO-DIGITAL MODULATOR WITH SENSOR FAILURE-MODE DETECTION
A pressure transmitter having a capacitance-to-digital modulator produces an output as a function of sensor capacitance and a reference capacitance. Transmitter also includes a sensor failure mode detector produces an output signal and identifies failure modes of the sensor capacitance and reference...
