Classification: CPC H | IPC H

Claim 13:
14. A low noise amplifier (LNA) comprising:
an input port;
an output port;
an amplifier circuit coupled to the input port and the output port, wherein the amplifier circuit comprises a plurality of transistors configured to provide an output signal to the output port based on an input signal received at the input port, wherein the plurality of transistors comprises a first transistor and a second transistor coupled to the first transistor, wherein the second transistor is configured to receive a bias voltage and amplify a signal from the first transistor to provide an amplified signal, and wherein the plurality of transistors is configured to provide the output signal based on the amplified signal;
a capacitive element having a first terminal and a second terminal, wherein the first terminal of the capacitive element is coupled to a gate of the first transistor of the plurality of transistors;
a capacitor switch having a first terminal and a second terminal, wherein the first terminal of the capacitor switch is coupled to the second terminal of the capacitive element, and wherein the second terminal of the capacitor switch is coupled to a source of the first transistor;
an inductive element coupled between ground and the source of the first transistor; and
an inductor switch coupled in parallel with at least a portion of the inductive element.
