A low power, high gain LNA topology

Abstract

A novel high gain and low noise amplifier topology is proposed. The proposed LNA topology is a current sharing two-stage cascade amplifier adopting a series inter-stage resonance. The performance of the proposed topology is compared with the existing high gain amplifiers, qualitatively and quantitatively. The simulation results at 2.4 GHz based on 0.35 /spl mu/m CMOS technology are also provided. The proposed topology demonstrates excellence over the existing high gain topologies in gain and noise figure.
