Abstract
A temperature sensing device and a temperature sensing method are provided. The temperature sensing device includes a sensor and an analog-to-digital converter. The sensor generates a first sensing result corresponding to an ambient temperature based on a first condition and generates a second sensing result corresponding to the ambient temperature based on a second condition. The second sensing result is different from the first sensing result. The analog-to-digital divides the first sensing result and the second sensing result to obtain a quotient value and generates an output digital code value corresponding to the ambient temperature according to the quotient value.
