Abstract
A temperature invariant reference voltage and a temperature variant physical quantity, such as a voltage or current, are generated. The temperature variant physical quantity changes in response to a temperature of the integrated circuit. A temperature sensor circuit generates a voltage that is linearly dependent on the temperature. A level generator circuit generates 2−1 voltage levels from the reference voltage. A comparator circuit, such as an analog-to-digital circuit, compares the voltage from the temperature sensor to the 2−1 voltage levels to determine which level is closest. An n-bit digital output of the resulting level is proportional to the temperature of the integrated circuit.
