Claim 17:
18. A method of adjusting a gain mode of a low noise amplifier (LNA), the method comprising:
selectively coupling a capacitive element of the LNA to a source of a first transistor of a plurality of transistors of the LNA to adjust the gain mode of the LNA, wherein the capacitive element has a first terminal and a second terminal, wherein the first terminal of the capacitive element is coupled to a gate of the first transistor, and wherein the second terminal of the capacitive element is selectively coupled to the source of the first transistor;
selectively shorting at least a portion of an inductive element of the LNA to ground to adjust the gain mode of the LNA, wherein the inductive element is coupled between ground and the source of the first transistor;
amplifying, by the first transistor, an input signal received at an input port of the LNA to provide a first amplified signal;
receiving, by a second transistor of the plurality of transistors, a bias voltage and the first amplified signal, wherein the second transistor is coupled to the first transistor;
amplifying, by the second transistor, the first amplified signal to provide a second amplified signal; and
providing, by the plurality of transistors, an output signal to an output port of the LNA based on the input signal, the second amplified signal, the selectively coupling, and the selectively shorting.
