Abstract: Provided is a band-gap reference voltage generator for low-voltage operation and high precision. The band-gap reference voltage generator minimizes voltage drop by connecting resistors in parallel to bipolar transistors, and cancels temperature dependence by properly adjusting a resistor of an output stage, so that it can provide a stable reference voltage that is unaffected by a change in temperature in spite of a low power supply voltage. Further, the band-gap reference voltage generator minimizes variation of the reference voltage caused by offset noise by switching of input and output voltages at input and output stages of a feedback amplifier, so that it can provide a precise reference voltage.
