A curvature-corrected bandgap reference comprising a first BJT device operating at a first current density that is substantially proportional to absolute temperature, the first BJT device having a first base-emitter voltage and a first base terminal and a second BJT device operating at a second current density that is substantially independent of temperature, the second BJT device having a second base-emitter voltage and a second base terminal. The first and second base terminals operate at a reference voltage. The reference voltage comprises a linear combination of the first and second base-emitter voltages and is thereby made substantially independent of temperature and curvature-corrected. The linear combination is provided by summing the first base-emitter voltage, a proportional to absolute temperature (PTAT) voltage proportional to a first current density, and a curvature-correction voltage proportional to a difference between the first and second base-emitter voltages.
