Abstract:
The present invention provides a thermal sensor integrated IC having a resistor and a converting circuit. The resistor is implemented by at least one metal line, wherein a resistance of the resistor is varied with a temperature of the resistor, the resistor has a first terminal and a second terminal, and one of the first terminal and the second terminal is arranged to provide a voltage signal corresponding to the resistance. The converting circuit is coupled to the resistor, and is configured to convert the voltage signal to an output signal for determining the temperature. In one embodiment, the at least one metal line is made by copper.
