Abstract
An electronic device may include wireless circuitry with a processor, a transceiver, an antenna, and a front-end module coupled between the transceiver and the antenna. The front-end module may include one or more power amplifiers for amplifying a signal for transmission through the antenna. A power amplifier may include multiple amplifier stages. Current sharing or reuse may occur between two amplifier stages in the power amplifier via a current flow path between the two amplifier stages. A power supply voltage line may be connected to the current flow path and may provide the downstream amplifier stage with a supplemental supply current based on which the downstream amplifier stage can amplify a radio-frequency signal received from the upstream amplifier stage.
