A bandgap reference voltage circuit is provided that substantially prevents noise sensitivity. The bandgap reference voltage circuit includes an operational amplifier, transistors, and a resistive element on one input of the operational amplifier. The resistive element substantially prevents noise from creating a non-zero mean change in current across one of the transistors. Thus, the resistive element substantially precludes noise from being rectified by a transistor, so that the output reference voltage of the bandgap reference voltage circuit is substantially stable and fixed.
