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

Claim 1:
2. The temperature sensor of claim 1, wherein the first plurality of currents comprises a first current and a second current that is different from the first current, wherein the sensing element outputs a first CTAT voltage and a third current based on the first current that passes through the sensing element, and the sensing element outputs a second CTAT voltage and a fourth current based on the second current that passes through the sensing element, wherein a first load voltage, a second load voltage, a third load voltage, and a fourth load voltage are generated across the load based on the third current, the first current, the fourth current, and the second current that pass through the load, respectively, wherein the plurality of CTAT voltages comprises the first CTAT voltage and the second CTAT voltage, the second plurality of currents comprises the third current and the fourth current, and the plurality of load voltages comprises the first load voltage, the second load voltage, the third load voltage, and the fourth load voltage, and wherein the temperature value is generated based on (i) the current density ratio and (ii) a difference between the second CTAT voltage and the first CTAT voltage.
