A reference circuit comprises a first current generator comprising a first transistor operably coupled to a second transistor and having respective base current corresponding to a positive temperature dependence of the reference circuit. A resistance is operably coupled to the first current generator and arranged to provide a second current corresponding to a negative temperature dependence of the reference circuit. A second current generator is operably coupled to the resistance and the first current generator that generates a combined current as a sum of the second current and base current. In this manner, the output voltage of the curvature compensated voltage and/or current reference circuit is substantially linear and substantially independent of the operating temperature of the circuit.
