Abstract:
1. A temperature sensor integrated on a silicon chip and comprising: first threshold means for detecting a first temperature threshold of a temperature of the silicon chip, the first temperature threshold having a first detection threshold; second threshold means for detecting a second temperature threshold of the temperature of the silicon chip, the second temperature threshold having a second detection threshold; third threshold means for detecting a third temperature threshold of the temperature of the silicon chip, the third temperature threshold being between the first and second temperature thresholds, and having a third detection threshold linked with the first detection threshold so that a deviation of the first detection threshold causes a corresponding deviation of the third detection threshold; and fourth threshold means for detecting a fourth temperature threshold of the temperature of the silicon chip, the fourth temperature threshold being between the first and second temperature thresholds, and having a fourth detection threshold linked with the second detection threshold so that a deviation of the second detection threshold causes a corresponding deviation of the fourth detection threshold; the third and fourth temperature thresholds defining a temperature window to test the temperature sensor for detecting deviation of the first and second detection thresholds.
