This document discusses low noise amplifier design. It begins with an outline and introduction. It then covers basic amplifier configurations like common-emitter, common-base, and common-collector. It discusses the cascode low noise amplifier configuration and how it improves frequency response and isolation. Feedback topologies like series and shunt feedback are also covered. The document provides explanations of noise figure, input matching, and how bias current affects noise. Design techniques like inductive input matching and the effect of Miller capacitance on matching are summarized.
