Abstract
In one embodiment, a power amplifier may include a bridge configuration having a first pair of gain transistors to receive a first portion of a differential signal and to amplify the first portion of the differential signal to an amplified first differential signal portion and a second pair of gain transistors to receive a second portion of the differential signal and to amplify the second portion of the differential signal to an amplified second differential signal portion. This second pair of gain transistors can be configured to be enabled in a first power mode and to be disabled in a second power mode.
