Provided is a reference voltage circuit which is resistant to change in temperature, and also can output the reference voltage of a low GND terminal with a low voltage and a low consumption current. The reference voltage circuit comprises a first NMOS transistor which is connected to a current mirror circuit and is connected to a drain by interposing a first resistance by a gate, and a second NMOS transistor which has a gate connected to the drain of the first NMOS transistor, is connected to a GND terminal by interposing a second resistance by a source, and has a threshold value voltage which is lower than the threshold value voltage of the first NMOS transistor. The reference voltage circuit outputs a reference voltage from the source of the second NMOS transistor. |
