A bandgap voltage generating circuit includes a circuit coupled to a first node and a second node, driving the first and the second nodes to the same voltage level. A first impedance element is coupled to the first node and a second impedance element is coupled to the second node, wherein the impedance of the second impedance element is larger than the impedance of the first impedance element. A first transistor is coupled to the first impedance element, and a second transistor is coupled to the second impedance element and the first transistor. The bandgap generating circuit generates a bandgap voltage at the second node.
