Abstract:
The present invention relates to an analog-to-digital converting circuit with temperature sensing and the electronic device thereof. The present invention uses a first impedance device to receive a reference voltage and produces an input current according to a temperature. An analog-to-digital converting unit is coupled to the first impedance device and produces a digital output signal according to the input current. Thereby, according to the present invention, by integrating the first impedance device into the analog-to-digital converting circuit, the circuit area and the power consumption can be lowered, which further reduces the cost and improves the accuracy of temperature sensing.
