A 1.2-V fully integrated 2.4-GHz low-noise amplifier in 0.35-mu m CMOS technology

Abstract

A 1.2-V fully integrated 0.35-mum inductively degenerated common source CMOS low-noise amplifier has been demonstrated at 2.4 GHz in this paper. A simple common source configuration can be operated at lower voltage and has lower output impedance when compared with a conventional high output impedance cascode LNA circuit topology. The input matching inductance, output matching inductance, and source degeneration inductance are integrated on a single chip. The fully integrated 2.4-GHz CMOS LNA has 5.27-dB power gain, 17-dB input return loss, 15413 output return loss, 4-dB noise figure, and -1-dBm IIPIdB and 8-dBm IIP3 at V-dd = 1.2 V and I-dd = 10 mA, respectively.
