The aim of this paper is to introduce a new differential LNA, based on current conveyors. This new LNA offers the following notable advantages over existent topologies: total absence of passive elements and thus it is now the smallest area differential LNA; wideband performances, with stable frequency responses from 0 to 3GHz and wideband matched input and output impedances; easy gain control over wide ranges (0 to 20dB). Comparisons with other topologies prove that the new implementation greatly advances the state of the art. This amplifier is ideally suited to today's multi-band receivers.
