Abstract
Abstract A temperature detector comprising temperature sensing circuitry, calibration circuitry, and power regular circuitry. The temperature sensing circuitry has an output that varies with 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 valve that represents the temperature. The power supply regulator circuitry coordinates power to the temperature sensing circuitry.
