A 1.2-V fully integrated 2.4-GHz low-noise amplifier in 0.35-μm CMOS technology.

A 1.2-V fully integrated 0.35-μm 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, 15-dB output return loss, 4-dB noise figure, and -1-dBm IIP1dB and 8-dBm IIP3 at Vdd = 1.2 V and Idd = 10 mA, respectively. © 2002 Wiley Periodicals, Inc.
