Abstract :
A low-power ultra-compact CMOS low-noise amplifier (LNA) in a shunt-resonating current-reused topology is presented. The common-source transistors are connected with a shunt-resonating inter-stage match network such that the bias current is shared to have low power consumption and RF signal is doubly amplified to have high gain and low noise figure. The implemented 0.18 mum CMOS LNA achieves 15.2 dB power gain and 3.0 dB noise figure, while only consuming 1.81 mW. Compared with previously published current-reused LNA, the proposed LNA has smallest chip size of 0.28 mm2, excluding the I/O pads, and the highest FOM of 2.77.
