Abstract:
1. An electronic device, comprising: a housing having an inner surface and an outer surface, wherein the inner surface is thermally coupled to the outer surface, which has an external temperature; and an integrated circuit, thermally coupled to the inner surface, including a sensor mechanism configured to measure a parameter associated with an internal temperature of the integrated circuit; and a thermoelectric device having a first end and a second end, wherein the first end is thermally coupled to the inner surface and the second end is thermally coupled to the integrated circuit, wherein the thermoelectric device is electrically coupled to the integrated circuit, and wherein the thermoelectric device is configured to output an electrical signal corresponding to a temperature difference between the external temperature and the internal temperature; and wherein the integrated circuit is configured to determine the external temperature based on the electrical signal and the measured parameter.
