Abstract

A voltage regulator for a plurality of radio frequency subcircuits of a radio frequency circuit. A first transistor configured to receive, based on a comparison between a reference voltage signal and a feedback signal, a bias signal corresponding to a desired regulated voltage for the plurality of radio frequency subcircuits, output the bias signal, and generate the feedback signal according to the bias signal as output from the first transistor. A second transistor configured to receive the bias signal as output from the first transistor and provide, based on the bias signal, the desired regulated voltage to a respective first one of the plurality of radio frequency subcircuits. A third transistor is configured to receive the bias signal as output from the first transistor and provide, based on the bias signal, the desired regulated voltage to a respective second one of the plurality of radio frequency subcircuits.
