A 9mW, 900-MHz CMOS LNA with 1.05dB-noise-figure

A 900-MHz CMOS Ultra-Low Noise Amplifier (LNA) has been integrated in a 0.35µm RF CMOS process with on-chip inductors. The LNA, housed in a standard TQFP48 package, features: Noise Figure NF=0.9dB with S11=-10.1dB, S22=-27dB, Power Gain Gp=14dB, input IP3=0dBm at Pdc=18mW. A NF=1.05dB is measured at Pdc=9mW. The reported LNA exhibits the best noise or power performance ever reported in CMOS technology.
