Claim 0:
1. A temperature sensor, comprising:
a sensing element configured to output, based on a first plurality of currents that passes through the sensing element, a plurality of complementary-to-absolute-temperature (CTAT) voltages and a second plurality of currents, wherein each current of the first plurality of currents is different; and
a load that is coupled to the sensing element, and has the first plurality of currents and the second plurality of currents pass therethrough, wherein a plurality of load voltages is generated across the load based on the first plurality of currents and the second plurality of currents, wherein a current density ratio of the temperature sensor is determined based on the plurality of load voltages, and wherein a temperature value indicative of a temperature sensed by the temperature sensor is generated based on (i) the current density ratio and (ii) the plurality of CTAT voltages.
