Abstract
Methods and devices for amplifying a plurality of input RF signals based on a multi-input cascode configuration is described. Transistors of stages of the multi-input cascode configuration are connected according to a tree, where there is at least one cascode transistor that is connected to at least two transistors of a stage below. In one case the stage below is an input stage, and in another case the stage below is a cascode stage. Activation and deactivation of transistors of the stages provide different conduction paths between the input stage and an output stage.
