Patent ID: 8058863

Claim:
A band-gap reference voltage generator comprising: first to third p-channel metal oxide semiconductor (PMOS) transistors of a current mirror having gates and sources connected in common to a first node and a power supply voltage, and drains respectively connected to second, third, and fourth nodes; a feedback amplifier having inverted and non-inverted input terminals respectively connected to the second and third nodes and an output terminal connected to the first node; first and second resistors respectively connected between the second node and a fifth node and between the second node and a sixth node; third and fourth resistors respectively connected between the third node and a seventh node and between the fourth node and a ground; first and second bipolar transistors having emitters respectively connected to the fifth node and the third node and collectors and bases connected to the ground; and fourth and fifth n-channel metal oxide semiconductor (NMOS) transistors respectively having gates and drains connected in common to the sixth node and the seventh node and sources connected to the ground, wherein a voltage between the fourth node and the ground is used as a reference voltage.
