Assignee: NXP B.V.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 2:
3. The temperature sensor of claim 2, further comprising a switching circuit that is coupled to the sensing element and the load,
wherein when the switching circuit operates in a first state, (i) the first current passes through the sensing element, and the sensing element outputs the first CTAT voltage and the third current based on the first current, and (ii) the third current passes through the load, and the first load voltage is generated across the load based on the third current,
wherein when the switching circuit operates in a second state, the first current passes through the load, and the second load voltage is generated across the load based on the first current,
wherein when the switching circuit operates in a third state, (i) the second current passes through the sensing element, and the sensing element outputs the second CTAT voltage and the fourth current based on the second current, and (ii) the fourth current passes through the load, and the third load voltage is generated across the load based on the fourth current, and
wherein when the switching circuit operates in a fourth state, the second current passes through the load, and the fourth load voltage is generated across the load based on the second current.
