ABSTRACT:
A temperature sensor comprises (a) a first voltage generating circuit that generates and outputs a first voltage having a positive or negative temperature coefficient in proportion to the absolute temperature; (b) a second voltage generating circuit that generates a second voltage having an opposite sign of temperature coefficient compared to the first voltage and outputs a reference voltage that does not have a temperature coefficient based on the second voltage; and (c) a comparator that compares the first voltage output from the first voltage generating circuit with the reference voltage output from the second voltage generating circuit.
