A low-voltage band-gap reference voltage bias circuit according to the present invention can provide a stable reference voltage at a supply voltage of about 1V or lower irrespective of a power supply voltage or temperature variation by flowing a PTAT mirror current into diodes and resistors and obtaining the average of voltages at two nodes. Furthermore, the low-voltage band-gap reference voltage bias circuit has simple configuration, reduces the resistance of a resistor that occupies a large chip area, uses small-sized diodes, and thus increases the integration density of the band-gap reference voltage bias circuit.
