A1V 6mW Inductorless Wideband LNA in 0.13μm RF CMOS

摘要

A wideband full integrated LNA without inductors is designed for low-voltage,low-power applications in 0.13μm CMOS technology. Based on the commongate-common-source (CG-CS) topology employing noise canceling,a negative feedback path is introduced between CS and CG paths for low-power operation. The proposed LNA exhibits 23dB voltage gain,1.9-2.4dB noise figure from 500MHz to 4GHz while only consuming 6mW power under 1V voltage supply.
