ABSTRACT:
According to an aspect of the present invention, there is provided a reference voltage generation circuit including: a first circuit configured to generate a first voltage that is independent of a power supply voltage and that is dependent of a temperature; a second circuit configured to generate a second voltage that is independent of the power supply voltage and that is dependent of the temperature; and a third circuit configured to compare the first voltage and the second voltage and to generate a reference voltage based on a higher one therebetween.
