Abstract

A 2.4 GHz subthreshold CMOS low‐noise amplifier (LNA) employing current‐reuse technique is presented for the first time. The circuit measuring 1050 × 723 μm^2^ is designed using CHRT's 0.18 μm RF CMOS technology. With the push–pull configuration, the amplifier simulated using Spectre® has a gain of 9.8 dB, IIP3 of −2.7 dBm, and NF of 3.6 dB, while consuming a mere 650 μA from a 1 V supply. © 2007 Wiley Periodicals, Inc. Microwave Opt Technol Lett 49: 743–744, 2007; Published online in Wiley InterScience (www.interscience.wiley.com). DOI 10.1002/mop.22292
