1. An apparatus for thermal management in an electronic device, the apparatus comprising:

  • integrated circuitry that includes an analog-to-digital converter (ADC), and a multiplexer having an output coupled to an input of the ADC;

    a resistor coupled to a first input of the multiplexer; and

    a thermistor coupled to a second input of the multiplexer, wherein the resistance of the resistor is about the same as the resistance of the thermistor when the thermistor is below a critical thermal bound of the electronic device.
