Classification: CPC G | IPC G

Claim 4:
5. The temperature sensor of claim 4, further comprising an analog-to-digital converter (ADC) that is coupled to the sensing element and the load,
wherein when the switching circuit operates in the first state, the ADC is configured to receive the first base voltage, the first emitter voltage, and the first load voltage, and output a first digital signal, a second digital signal, and a third digital signal that are indicative of voltage levels of the first base voltage, the first emitter voltage, and the first load voltage, respectively,
wherein when the switching circuit operates in the second state, the ADC is further configured to receive the second load voltage and output a fourth digital signal that is indicative of a voltage level of the second load voltage,
wherein when the switching circuit operates in the third state, the ADC is further configured to receive the second base voltage, the second emitter voltage, and the third load voltage, and output a fifth digital signal, a sixth digital signal, and a seventh digital signal that are indicative of voltage levels of the second base voltage, the second emitter voltage, and the third load voltage, respectively, and
wherein when the switching circuit operates in the fourth state, the ADC is further configured to receive the fourth load voltage and output an eighth digital signal that is indicative of a voltage level of the fourth load voltage.
