Abstract A CMOS low noise amplifier (LNA) for low‐power ultra‐wideband wireless applications is presented. To achieve low power consumption and wide operating bandwidth, the proposed LNA uses a current‐reused technique and a simple high‐pass input matching network. This work is implemented in 0.18‐μm CMOS process technology and shows a 3.1–10.6 GHz bandwidth. With only 1.5 V supply voltage, the LNA can achieve power flat gain of 13.2 dB with input matching of −10.3 dB, the minimum noise figure of 3.33 dB, and input third‐order‐intercept point (IIP3) of −3.3 dBm. The power dissipation is only 9.3 mW. © 2009 Wiley Periodicals, Inc. Microwave Opt Technol Lett 51: 2077–2080, 2009; Published online in Wiley InterScience (www.interscience.wiley.com).
