Abstract
A voltage regulator for a radio frequency circuit including a master regulator circuit, a first slave regulator circuit, and a first radio frequency subcircuit. The master regulator circuit is configured to i) receive a reference voltage signal and a feedback signal and ii) output a control voltage signal based on the reference voltage signal and the feedback signal. The first slave regulator circuit is configured to i) receive the control voltage signal and ii) output a first regulated supply voltage signal based on the control voltage signal. The first radio frequency subcircuit is configured to receive the first regulated supply voltage signal. The control voltage signal corresponds to a desired supply voltage for the first radio frequency subcircuit.
