System and method for a low noise amplifier

摘要

An embodiment described herein includes a low noise amplifier (LNA) including a plurality of separate input terminals, a plurality of transistors, and an output network coupled to a first reference terminal and a single output of the LNA. Each transistor includes a conduction path and a control terminal coupled to one of the plurality of separate input terminals. The output network is also coupled to the conduction path of each of the plurality of transistors.
