Abstract
A LNA (low-noise amplifier) includes a matching network configured to provide a three-way coupling between an input node, a matched node, and a source node; a gate capacitor configured to provide AC (alternate current) coupling between the matched node and a gate node; a cascode amplifier configured to receive a gate voltage at the gate node and output an output voltage at an output node in accordance with a source degeneration at the source node; and a load network connected to the output node, wherein the matching network having a shunt inductor and a series inductor that are overlapped in layout to have a strong mutual coupling and a source degenerating inductor that is laid out in a close proximity to the shunt inductor to have a strong mutual coupling.
