A wideband 0.18μm CMOS LNA with RC-feedback topology for UWB applications

A 0.18 mum CMOS low noise amplifier using RC-feedback topology is proposed with optimized matching, gain, noise, linearity and area for UWB applications. The IC prototype achieved 9.5 dB of average power gain, low 3.4 dB noise figure (NF), -9.2 dB input match, -13.5 dB return loss, -6 dBm of IIP3 and only 0.54 mm

size with 15 mW power consumption. Good agreement between the simulated and measured results is found.
