Abstract

We have proposed a 3.1–4.8 GHz CMOS wideband low noise amplifier (LNA) for ultra wideband system. The LNA is fabricated with the 0.18‐μm 1P6M standard CMOS process. Measurement of the CMOS LNA was performed using RF probe station. From 3.1 to 4.8 GHz, the wideband LNA exhibits a noise figure of 3.3–3.7 dB, a gain of 12.8–13.9 dB, and an input/output return loss higher then 9.4/7.3 dB. The input IP3 (IIP3) at 4.1 GHz is +1.25 dBm, and consumes 16.5 mW of power. © 2008 Wiley Periodicals, Inc.
