A 900 MHz to 5.2 GHz dual-loop feedback multi-band LNA

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… (More)
