A gate-source transformer feedback is utilized for the simultaneous noise and impedance matching. In order to achieve high gain with limited dc power consumption (P dc), a single-ended neutralization technique is applied to the circuit. According to measurement, the proposed K-band LNA achieves a 19.1-dB small signal gain with 2.8-GHz 3-dB bandwidth (21.2-24 GHz) and noise figure of 3.6 dB with only 0.99 mW P dc. To the best of author's knowledge, this LNA shows the highest figure of merit (FoM), which is 7071 1/W, among published K-band low-power LNAs. ? 2001-2012 IEEE. |
