Abstract

A reference voltage circuit () includes a PTAT voltage generation circuit () that generates a voltage with a positive temperature coefficient, a CTAT voltage generation circuit () that generates a voltage with a negative temperature coefficient, and a temperature characteristic adjustment circuit () that generates a voltage for adjusting temperature characteristics. The reference voltage circuit outputs a reference voltage (VOUT) formed by calculation based on the output of the PTAT voltage generation circuit, output of the CTAT voltage generation circuit, and output of the temperature characteristic adjustment circuit.
