Patent ID: 7705682

Claim:
A method comprising: receiving a first input signal at a first terminal of a first amplifier; amplifying the first input signal using the first amplifier, wherein the first amplifier is coupled to one or more source degeneration inductors at a second terminal of the first amplifier and to one or more load inductors at a third terminal of the first amplifier; receiving a second input signal at a first terminal of a second amplifier; amplifying the second input signal using the second amplifier, wherein the second amplifier is coupled to the one or more source degeneration inductors at a second terminal of the second amplifier and to the one or more load inductors at a third terminal of the second amplifier; receiving a third input signal at a first terminal of a third amplifier; amplifying the third input signal using the third amplifier, wherein the third amplifier is coupled to the one or more source degeneration inductors at a second terminal of the third amplifier and is coupled to the one or more load inductors at a third terminal of the third amplifier; receiving a fourth input signal at a first terminal of a fourth amplifier; and amplifying the fourth input signal using the fourth amplifier, wherein the fourth amplifier is coupled to the one or more source degeneration inductors at a second terminal of the fourth amplifier and is coupled to the one or more load inductors at a third terminal of the fourth amplifier, wherein the one or more source degeneration inductors is coupled to the second terminal of the third amplifier and the second terminal of the fourth amplifier through one or more switches.
