Abstract: A system includes a first module, a second module, and a third module. The first module determines a first temperature and a first power dissipation value of a thermistor based on a resistance of a first resistor connected in series with the thermistor. The second module, after disconnecting the first resistor and connecting a second resistor in series with the thermistor, determines a second temperature and a second power dissipation value of the thermistor based on a resistance of the second resistor. The third module determines a thermal dissipation factor based on the first and second temperatures and the first and second power dissipation values, and corrects temperature sensed by the thermistor based on the thermal dissipation factor.
