Abstract:
A voltage regulator includes a band limited reference voltage. The band limited reference voltage is generated from a supply voltage combined with a feedback path to provide a band reject power supply rejection ratio (PSRR). The voltage regulator also includes a feedforward path to extend the band reject PSRR.
