A built-in calibration device is for a temperature sensor. A voltage divider is configured for receiving one reference voltage with a negative temperature coefficient and generating a plurality of input voltages. Comparing apparatus is connected to the voltage divider and configured for generating a plurality of comparing codes based upon another reference voltage with a positive temperature coefficient and the plurality of input voltages. Controlling apparatus is connected to the comparing apparatus and configured for calibrating the temperature sensor based on the plurality of comparing codes.
