Abstract

Power amplification devices are described, which are configured to amplify a radio frequency (RF) transmission signal. The power amplification device includes a voltage regulation circuit and a power amplification circuit. The voltage regulation circuit is configured to generate a regulated voltage for the power amplification device from a supply voltage and to adjust a regulated voltage level of the regulated voltage in accordance with a voltage adjustment gain. The voltage adjustment gain of the voltage regulation circuit is set by a feedback resistance. To help prevent the voltage regulation circuit from saturating, the voltage regulation circuit adjusts the feedback resistance to reduce the voltage regulation gain.
