    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: An RFIC configuration for reduced antenna trace loss is disclosed. In an exemplary embodiment, an apparatus includes a primary RFIC and a secondary RFIC that is configured to receive analog signals from at least two antennas. The secondary RFIC is configured to process selected analog signals received from at least one antenna to generate an analog output that is input to the primary RFIC.
