Abstract

A wideband full integrated LNA without inductors is designed for low-voltage, low-power applications in 0.13 μm CMOS technology. Based on the common-gate-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 23 dB voltage gain, 1.9-2.4 dB noise figure from 500 MHz to 4 GHz while only consuming 6 mW power under 1 V voltage supply.
