A miniature lowpower ultrawideband low noise amplifier in 0.18 m CMOS Academic Article uri icon


  • A 0.18-m 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 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. 2011 Wiley Periodicals, Inc.
