Abstract

The present invention provides a voltage generation circuit which outputs high-precision output voltage in a wide temperature range. A semiconductor device has a voltage generation circuit. The voltage generation circuit has a reference voltage generation circuit which outputs reference voltage, and a plurality of correction circuits for generating a correction current and making it fed back to the reference voltage generation circuit. The correction circuits generate sub correction currents which monotonously increase from predetermined temperature which varies among the correction circuits toward a low-temperature side or a high-temperature side. The correction current is sum of a plurality of sub correction currents.
