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.

Claim (Index 24):
An apparatus comprising:\n multiple band-pass filters having different frequency bands, the multiple band-pass filters configured to filter a received signal to produce a filtered signal; a switch module connected to the multiple band-pass filters, the switch module configured to connect a selected band-pass filter of the multiple band-pass filters to provide the filtered signal; an amplifier circuit connected to the switch module, the amplifier circuit including at least two amplifier branches, the amplifier circuit configured to amplify the filtered signal that is provided by the switch module using one or more of the at least two amplifier branches; and multiple inductors including:\n an input inductor having an inductance, the input inductor connected between the switch module and the amplifier circuit; and \n at least two degeneration inductors having other inductances, the at least two degeneration inductors respectively connected between the at least two amplifier branches of the amplifier circuit and a ground, the at least two degeneration inductors magnetically coupled to each other and the input inductor with respective coupling coefficients, \n the multiple inductors configured to cause an input impedance associated with the amplifier circuit and the multiple inductors to approximately equal an output impedance of the selected band-pass filter based on the respective coupling coefficients, the inductance of the input inductor, and the other inductances of the at least two degeneration inductors.
