Abstract

In this paper, a wideband low noise amplifier (LNA) with local active feedback is proposed. The proposed LNA exploits a differential common-source stage with current-reuse technique to reduce the power consumption. A source follower is utilized as an active feedback path and the feedback signal is taken preceding the cascode transistor to broaden the bandwidth and improve the linearity. Implemented in a 130-nm SOI CMOS technology, the proposed LNA achieves simulated 21.1 dB voltage gain with a 3-dB bandwidth of 0.5-5.6 GHz without using any inductors. The minimum NF is 3.63 dB while the maximum IIP3 is-4.86 dBm. The power consumption is 15.2 mW under a supply voltage of 1.5 V.
