ABSTRACT:
An electrical circuit is disclosed that is capable of improving the power supply rejection ratio of a standard bandgap reference while maintaining the temperature coefficient of the standard design. One embodiment of the circuit comprises a bandgap reference voltage generator, an operational amplifier, a transistor, a voltage divider, a startup network, and a self-biasing network that provide a voltage reference with improved characteristics.
