Abstract:
A bandgap voltage reference circuit configured to generate a bandgap reference voltage is provided. The bandgap voltage reference circuit includes a bandgap current generating circuit, a differential pair circuit and a flipped voltage follower. The bandgap current generating circuit converts the bandgap reference voltage into a bandgap current and generates a first voltage and a second voltage according to the bandgap current. The differential pair circuit is coupled to the bandgap current generating circuit to receive the first voltage and the second voltage and configured to reduce a voltage difference between the first voltage and the second voltage and generate a third voltage. The flipped voltage follower is coupled to the differential pair circuit to receive the third voltage and generates the bandgap reference voltage accordingly.
