Abstract
A temperature sensing device and a calibration method of the temperature sensing device are provided. Based on different conditions, the temperature sensing device generates a first digital sensing value and a second digital sensing value corresponding to an ambient temperature. The temperature sensing device generates a first sensing result value according to the first digital sensing value, a first compensation value, and a sensing difference value between the first digital sensing value and the second digital sensing value, and generates a second sensing result value according to the second digital sensing value, a second compensation value, and the sensing difference value. The temperature sensing device obtains an error from the first sensing result value and the second sensing result value according to a first reference value and a second reference value. The temperature sensing device calibrates the first compensation value according to the error.
