Patent number: 11119134Abstract: 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.
