Abstract
A MEMS pressure sensor includes a multiplexer passing a first-voltage or a second-voltage as output, an analog front-end (AFE) conditioning the output of the multiplexer to produce an ADC input, an analog-to-digital converter (ADC) digitizing the ADC input to produce an ADC output, a first Wheatstone-bridge sensitive to pressure and generating the first-voltage based upon the sensed pressure, a second Wheatstone-bridge sensitive to temperature generating the second-voltage based upon the sensed temperature, a voltage regulator using the first Wheatstone-bridge or the second Wheatstone-bridge in a feedback resistive-divider to generate a regulated-voltage, and control circuitry causing the voltage regulator to use the first Wheatstone-bridge during a pressure sensing period, and causing the voltage regulator to use the second Wheatstone-bridge during a temperature sensing period. The AFE and ADC are powered by the regulated-voltage, and the AFE and ADC use a feedback-voltage generated by the feedback resistive-divider as a reference-voltage.
