ABSTRACT:
A low voltage bandgap reference circuit based on a current summation technique where reference voltages with positive and negative temperature coefficients are generated by a first circuit. These reference voltages are coupled to amplifying circuits which generate reference voltages with equal and opposite temperature coefficients based on the ratio of resistors in these amplifying circuits, thereby producing a temperature independent reference voltage. The current from each of these amplifying circuits is then summed in a summing resistor, where the size of the resistor determines the magnitude of the temperature independent reference voltage.
