Zusammenfassung:Provided herein are apparatus and methods for low voltage high power supply rejection ratio (PSRR) systems. A charge pump converts a supply voltage to a larger charge pump voltage and provides the charge pump voltage to a circuit subsystem. The charge pump voltage is regulated to a state dependent reference. In the steady state the charge pump voltage is regulated with respect to an output voltage of the circuit subsystem; in this way PSRR of the circuit subsystem is enhanced.
