A complementary metal-oxide-semiconductor (CMOS) switching system with increased supply rejection is disclosed. The system comprises a voltage regulator and a CMOS circuit. The voltage regulator receives a supply voltage and generates a regulated voltage by regulating an amplitude of the received supply voltage. The CMOS circuit includes an input terminal to receive a first voltage, switching circuitry to selectively couple the CMOS circuit to the voltage regulator in one of a plurality of configurations, and an output terminal to output a second voltage based at least in part on the first voltage and the regulated voltage when the CMOS circuit is coupled to the voltage regulator in a first configuration of the plurality of configurations.
