A ratiometric temperature measurement system includes a sensing circuit to measure a temperature and a controller to determine a resistance corresponding to the sensing circuit. The sensing circuit includes a temperature sensing circuit and a current sensor. The sensing circuit utilize an electrical current to output a first voltage indicative of a first voltage differential across the temperature sensing circuit and to output a second voltage indicative of a second voltage differential across the current sensor. The controller is configured to determine a resistance corresponding to the temperature sensing circuit based at least in part on the first and second voltage differentials. The controller determines a temperature value indicative of the measured temperature based on the resistance.
