ABSTRACT:
A bandgap reference circuit is provided in which the conventional current loop with a current mirror for feeding a differential amplifier is replaced by a reference current that flows through a resistor connected to the bias input of the differential amplifier. In conjunction with a simpler construction and suitability for lower supply voltages, the circuit exhibits an improved supply voltage rejection PSRR over the prior art.
