Abstract: A detector for measuring a resistance of a variable resistance sensor (VRS) that varies with respect to a time-varying stimulus (e.g., temperature) includes a voltage reference having variation with respect to operating conditions and a linearized digital-to-analog converter (LIDAC) having a known transconductance that uses the voltage reference to generate a current for pumping into the VRS to cause the VRS to generate a voltage sensed by the detector. The sensed voltage includes error due to the variation of the voltage reference. The detector also includes a programmable gain amplifier (PGA) that gains up the sensed voltage to generate an output signal, an ADC that converts the output signal to a digital value, and a digital processor that computes the resistance of the VRS using the digital value and the known transconductance. The PGA is non-varying with respect to the time-varying stimulus.

Abstract: A system includes a first sensed voltage generated as a product of the first voltage reference and an unknown scalar, a second sensed voltage generated as a product of the first voltage reference and a known scalar, and an amplifier having gain error that generates a second voltage reference (first voltage reference or scaled version thereof). An ADC uses the second voltage reference to generate first and second digital values, representing the first and second sensed voltages, that contain error caused by the second voltage reference gain error. A processor uses the known scalar and a ratio based on the first and second digital values to remove the error from the first digital value. The first sensed voltage may be generated by pumping a current into a variable resistance sensor (VRS) whose resistance varies with respect to a time-varying stimulus (e.g., temperature) and is proportional to the unknown scalar.
