A Novel 5-5.7GHz Low-Power LNA Using Low-Power Techniques

Abstract

In this paper, a novel 5-5.7GHz low power low noise amplifier (LNA) is designed. It utilizes two stage structures, including common-source structure adopting self-forward-body-bias (SFBB) technique, improved input matching and output matching methods. In 5-5.7GHz band, simulation results shows the design has gain greater than 16.5dB, operating voltage lower than 1V and low noise figure.
