Abstract
This paper demonstrates a multi-band low noise amplifier (LNA) in 0.13µm CMOS process, which is configurable with switching capacitor in 900MHz, 1800MHz, 2.4GHz and 5.2GHz bands. A dual-loop feedback technique is used to enhance the performance in noise figure, power gain and power consumption. The noise figures are 2.6dB at 900MHz, 2dB at 1800MHz, 2.1dB at 2.4GHz and 3.5dB at 5.2GHz; and the power gains are 17dB at 900MHz, 21dB at 1800MHz, 26dB at 2.4GHz and 19dB at 5.2GHz in post-simulation. The S 11 in all of the bands is below −10dB by wideband matching. The LNA consumes 3.92mW from 1 V supply.
