    Abstract: A power amplifier stage including multiple amplifier branch circuits, in which each amplifier branch circuit includes a cascode device, a source device, and a replica cascode device. The cascode device has current terminals coupled between an output node and an intermediate node, and has a control terminal receiving a corresponding activation signal. The source device has current terminals coupled between a supply reference node and the intermediate node, and has a control terminal receiving an input signal. The replica cascode device has current terminals coupled between a supply node and the intermediate node, and has a control terminal receiving a corresponding complementary activation signals. An output power level of the power amplifier stage is controlled by asserting a selected number of activation signals and corresponding complementary activation signals for activating a selected number of the amplifier branch circuits.
