摘要

A 0.18-μm CMOS low-noise amplifier (LNA) operating over the entire ultra-wideband (UWB) frequency range of 3.1-10.6 GHz, has been designed, fabricated, and tested. The UWB LNA achieves the measured power gain of 7.5 ± 2.5 dB, minimum input matching of -8 dB, noise figure from 3.9 to 6.3 dB, and IIP3 from - 8 to —1.9 dBm, while consuming only 9 mW over 3-10 GHz. It occupies only 0.55 x 0.4 mm2 without RF and DC pads. The design uses only two on-chip inductors, one of which is such small that could be replaced by a bonding wire. The gain, noise figure, and matching of the amplifier are also analyzed.
