LOW NOISE BANDGAP VOLTAGE REFERENCE CIRCUITS

Voltage reference circuits configured to output reference voltages with a reduced noise on the output and reduced power consumption when compared to other arrangements of voltage reference circuits. The voltage reference circuit of this disclosure may stack two or more independent shunt voltage reference circuits in series to produce a summed voltage (Vsum), then amplify the summed voltage to output the desired reference voltage. The circuit of this disclosure may arrange the independent shunt voltage reference circuits to diminish any noise generated by each independent shunt voltage reference circuit in the summed voltage, for example as an array of independent shunt voltage reference circuits in series.
