Reference voltage generation circuit

Object of the present invention is to provide a reference voltage generating circuit, which may provide a relatively not affected by the ambient temperature, and the reference voltage in a bandgap voltage of silicon or less, and, the reference voltage generating circuit generating a current comprises current generation circuit and a current converting current generating circuit generates a voltage and generates a current-voltage conversion circuit reference voltage, a current generating circuit generates in accordance with the current generated temperature around the circuit and the value of current, current-voltage conversion circuit changes have performed voltage conversion, and has two current generating circuit resistance current generated flows, either one of two resistors having a positive temperature coefficient, the remaining one has a negative temperature coefficient.
