ABSTRACT:
A system and method are disclosed for providing a low voltage bandgap reference circuit that provides a substantially constant output voltage over a range of values of temperature. For example, the bandgap reference circuit could be capable of providing output voltages that are as low as one hundred millivolts. Also, no special start-up circuitry may be required to initiate the operation of the bandgap reference circuit. The bandgap reference circuit could further require fewer transistors and fewer resistors than prior art bandgap reference circuits.
