A reconfigurable low-noise amplifier (LNA) with tunable input matching network is proposed. The tunable input matching network provides continuous tuning of the input resonant circuit. The LNA is implemented using 0.13-μm CMOS technology. The amplifier has a tuning range of 1.9-2.4 GHz with an input return loss better than -13 dB. The LNA has a measured voltage gain of 10-14 dB and a noise figure of 3.2-3.7 dB within the band. The LNA consumes 14 mA from a 1.2-V supply. The detailed analysis of the proposed LNA, including the tuning range and additional noise of the proposed reconfigurable input matching network, is presented. To our knowledge, this is the first architecture that provides continuous tuning of the input matching network. © 2009 IEEE.
