DUAL VOLTAGE REGULATOR FOR A SUPPLY VOLTAGE CONTROLLED POWER AMPLIFIER IN A CLOSED POWER CONTROL LOOP

摘要

A supply voltage controlled power amplifier that comprises a power amplifier, a closed power control feedback loop configured to generate a power control signal, and a dual voltage regulator coupled to the power control feedback loop, the dual voltage regulator comprising a first regulator stage and a second regulator stage, wherein the closed power control loop minimizes noise generated by the first regulator stage.
