This paper presents an energy efficient wideband Low Noise Amplifier (LNA) operating in subthreshold regime. Wideband matching and low noise figure in subthreshold domain is achieved by using a gate inductor assisted impedance matching and a current reuse feed-forward noise cancellation technique, respectively. Fabricated in UMC 0.18 μm CMOS technology, the proposed LNA draws 1 mA from 1.8 V supply and achieves a voltage gain of 13 dB (taking into account a 8 dB loss in buffer), minimum Noise-Figure (NFmin) of 6 dB, and 3 dB bandwidth from 2 GHz to 5 GHz.
