Voltage regulator for high performance RF systems

摘要

A radio frequency transceiver for a wireless communications device transceiver comprising a plurality of subcircuits, a first regulator circuit, and a plurality of second regulator circuits. Each subcircuit is configured to perform an operation of the radio frequency transceiver in accordance with a corresponding regulated voltage. A first regulator circuit is configured to provide a bias signal based on a reference signal and a feedback signal indicative of the bias signal. The bias signal corresponds to a desired regulated voltage for the plurality of subcircuits. A plurality of second regulator circuits corresponding to respective ones of the plurality of subcircuits are each configured to provide the regulated voltage to the respective one of the plurality of subcircuits.
