Temperature measuring devices and related methods

摘要

Exemplary embodiments are disclosed herein of temperature measuring devices. In an exemplary embodiment, a temperature measuring device includes a temperature sensing means, at least two reference voltage sources, and a reference voltage selection means for selecting one reference voltage source from the at least two reference voltage sources to generate a reference voltage output. The temperature measuring device also includes an A/D converter for converting an analog signal output by the temperature sensing means to a digital signal based on the reference voltage output. The temperature measuring device further includes a temperature calculation means for calculating a temperature to be measured based on the digital signal output by the A/D converter.
