摘要：
A bandgap reference circuit includes a circuit for high-order temperature curvature compensation; and a circuit for low output impedance and current drive capability, wherein an output voltage of the bandgap reference circuit can be independently adjusted to be either above or below a silicon bandgap voltage without impacting temperature curvature.
