Abstract: PROBLEM TO BE SOLVED: To provide a band gap voltage reference circuit which has a low supply voltage and which is not affected by temperature by using an absolute temperature proportional (PTAT) voltage generator and the band gap voltage reference circuit containing a voltage buffer. SOLUTION: The first stage 190 of a band gap voltage reference circuit 100 is an absolute temperature proportional (PTAT) voltage generator driven by a current source 150. A second stage 192 is used as a voltage buffer and it supplies voltage VR1 applied to a load resistance 110 and voltage VBG obtained from voltage between the bases and the emitters of PNP transistors 106 and 108 of the PTAT voltage generator 190. Since voltages VBE1 and BBE2 between the bases and the emitters of the PNP transistors 106 and 108 are almost linearly reduced with a temperature, the temperature depending change of voltage VBE2 on the PNP transistor 108 is added to standardized voltage VR1 appearing on both ends of the load resistance 110. Thus, voltage irrespective of the temperature is realized.
