This paper presents a low-power noise-matched fully-differential common-gate (CG) low noise amplifier (LNA) for ultrawideband receiver operating in the full 3.1-10.6 GHz band. Performance was optimized by employing the transconductance %26apos;g (m) %26apos; boosted CG LNA topology with series peaking along with an input noise matching network. A common source g (m) -boosting amplifier, in conjunction with an LC T-network, was used to share the bias current with the CG stage. The LNA was demonstrated using a 130 nm IBM CMOS process technology and it consumed 7 mW from a 1 V supply. It exhibited an input return loss (S-11) and an output return loss (S-22) of -10.5 and -14 dB respectively. In addition, it also achieved a forward power gain (S-21) of 14.5 dB and a noise figure between 4.5 and 5.0 dB.
