Abstract

A temperature detector comprises temperature sensing circuitry calibration circuitry, and power regular circuitry. The temperature sensing circuitry has an output that varies with a temperature to create a temperature variation. The calibration circuitry is coupled to receive the output that varies with temperature to create a temperature variation. The calibration circuitry interprets the temperature variation and outputs a value that represents the temperature. The power supply regulator circuitry coordinates power to the temperature sensing circuitry. Alternate embodiments of the temperature detector comprise temperature sensing circuitry, calibration circuitry, and resolution enhancement circuitry. The temperature sensing circuitry has an output that varies with a temperature to create a temperature variation. The calibration circuitry is coupled to receive the output that varies with temperature to create a temperature variation. The calibration circuitry also interprets the temperature variation and outputs a value that represents the temperature. The value has a resolution. The resolution enhancement circuitry is coupled to the calibration circuitry that enhances the resolut…
