Abstract
In this paper, we present the low noise amplifier using new feedback connection configurations. The UWB LNA is design in 0.18 µm TSMC CMOS technique to achieve high gain, small size and low noise. The LNA achieved 11 dB of average power gain, low 2.87 dB noise figure (NF), −10.9 dB input match, −7 dB return loss, −3 dBm of IIP3 and only 0.54 mm2 size with 15 mW power consumption.
