摘要：
This brief 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 cancelation technique, respectively. Fabricated in UMC 0.18-mu m 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 to 5 GHz.
