A bandgap reference circuit that uses reduced substrate area while requiring relatively low voltage. The circuit may include a bipolar transistor with a resistor electrically connected across the emitter-base of the bipolar transistor. The resistor sums a first current with a second current and also generates a fractional VEB. The bandgap reference circuit may have a first current proportional to VEB, and a second current proportional to a PTAT current. An impedance booster may be incorporated into the circuit. Also disclosed is a method of regulating a voltage level using embodiments of the bandgap reference circuit.
