摘要

A novel wideband dual-feedback low noise amplifier (LNA) implemented in standard 0.18 μm CMOS process is proposed in this paper. The proposed dual feedback topology can improve the total noise contribution for LNA design. By exploiting the gate-inductive bandwidth gain-enhancement (GIBE) technique, the LNA can extend the more than 30 % bandwidth and enhance gain an overall bandwidth of DC to 5 GHz. Besides, the fabricated LNA with the current-mirror circuit consumes a power of 10.4 mW. The proposed LNA achieves an average gain of 13.9 dB and a minimum noise figure (NF) of 2.76 dB from DC to 5 GHz. The LNA achieves a good figure-of-merit (FoM) of 3.8. The chip area is 0.45 mm 2 with all pads and dummy blocks.
