A 1.2 V 3.1–10.6 GHz CMOS low noise amplifier with 24 dB gain and 2.4 dB noise figure

This paper presents a 3.1-10.6 GHz low noise amplifier (LNA) for ultra-wideband (UWB) applications. The proposed wideband amplifier comprises a single-ended resistor feedback LNA with wideband input matching and a single-to-differential voltage buffer which improves the power gain of the amplifier. The LNA achieves a 23.2 dB voltage gain and input return loss below -13 dB from 3.1-10.6 GHz, 2.4 dB and 2.7 dB minimum and maximum noise figure (NF), and -11.9 dBm IIP3 at 6 GHz. The proposed LNA is realized in 0.13 ¿m CMOS technology and occupies 0.32 mm
