A gm-boosted resistive feedback low-noise amplifier (LNA) using a series inductor matching network and its application to a 2.4 GHz LNA is presented. While keeping the advantage of easy and reliable input matching of a resistive feedback topology, it takes an extra advantage of gm-boosting as in inductively degenerated topology. The gain of the LNA increases by the Q-factor of the series RLC input network, and its noise figure (NF) is reduced by a similar factor. By exploiting the gm-boosting… CONTINUE READING
