Abstract
The present application discloses various implementations of a mobile device including a power amplifier (PA) having a driving stage coupled to an output stage. The driving stage is configured to be selectably powered by one of a first voltage supply and a second voltage supply. The output stage is configured to be powered by the second voltage supply. The mobile device further includes a voltage supply selection switch configured to selectably power the driving stage by the second voltage supply when an output power of the PA is less than or equal to a threshold power.
