Abstract
A bandgap reference circuit with curvature compensation. The circuit includes a first current mirror that mirrors the current conducted by the bandgap reference. A difference between the gate-to-source voltages in the two legs provides a first mirrored current with non-linear temperature stability. This first mirrored current is again mirrored by a second current mirror in which the mirror transistors also have differing gate-to-source voltages, with the current from this second current mirror coupled to the bandgap reference to compensate for curvature in the CTAT current over temperature.
