Claim 14:
15. A system, comprising:
a temperature sensor including:
a power source;
a diode electrically connected to the power source;
a resistor in series with the diode; and
a heater proximate to the diode;
wherein the power source is operable to apply a voltage across the diode; and

a circuit configured to:
apply a first set of voltages across the diode, wherein the first set of voltages includes a first applied voltage (V1), a second applied voltage (V2), and a third applied voltage (V3);
detect a second set of voltages, wherein the second set of voltages includes a first detected voltage (VD1), a second detected voltage (VD2), and a third detected voltage (VD3); and
determine the temperature proximate to the circuit based on the first set of voltages and the second set of voltages.
