Abstract: An integrated circuit is disclosed for gain-dependent impedance matching and linearity. The integrated circuit includes at least two amplifier branches, an input inductor, and at least two degeneration inductors. Each amplifier branch includes a node, an input transistor, and a cascode stage connected between a drain of the input transistor and the node. Respective nodes of the at least two amplifier branches are connected together and respective gates of the input transistors of the at least two amplifier branches are connected together. The input inductor is connected to the respective gates, and the at least two degeneration inductors are connected between respective sources of the input transistors of the at least two amplifier branches and a ground. The at least two degeneration inductors are configured to establish a magnetic coupling with the input inductor and establish another magnetic coupling between each other.

Abstract: A method of selecting a mode for an SPS receiver includes selecting either a first mode or a second mode for the SPS receiver based on a comparison between an output power of a communications transceiver and a mode switch point wherein the mode switch point is a power value. The first mode corresponds to a first bias current value of the SPS receiver, the second mode corresponds to a second bias current value of the SPS receiver, and the first bias current value is different from the second bias current value.
