Abstract
A system and method of measuring a temperature including applying a first set of voltages across a circuit in sequence; detecting a second set of voltages corresponding to the first set of voltages, wherein the second set of voltages includes a first detected voltage, a second detected voltage, and a third detected voltage, wherein the first applied voltage corresponds to the first detected voltage, the second applied voltage corresponds to the second detected voltage, and a third applied voltage corresponds to the third detected voltage; modifying an output of a heater proximate to the diode within the circuit, wherein a combined heat dissipation of the heater and the diode remains constant during operation of the circuit; and determining a temperature proximate to the diode based on the first set of voltages and the second set of voltages.
