Temperature sensing device and temperature sensing method

The invention provides a temperature sensing device and a temperature sensing method. The temperature sensing device comprises a sensor and a conversion circuit. The sensor generates a first sensing signal and a second sensing signal corresponding to an ambient temperature based on different conditions. The conversion circuit performs subtraction on the first sensing signal and the second sensing signal to obtain a result difference value, calculates a compensation value according to the result difference value and the first sensing signal, performs multiplication on the result difference value and the compensation value to obtain a multiplication value, and subtracts the multiplication value from the first sensing signal to generate a first value. The multiplication value is added to the first sensing signal to produce a second value, and the first value is divided by the second value to produce an output value. The second value is a constant. 本发明提供一种温度感测装置以及温度感测方法。温度感测装置包括传感器以及转换电路。传感器基于不同条件产生对应于环境温度的第一感测信号
