Abstract :
An ultra-wideband low noise amplifier employs shunt resistive feedback is presented. LNA chip area has been reduced significantly using active inductor load. The LNA is designed and fabricated in the standard 0.18μm CMOS technology. The UWB LNA exhibit a measured gain of 12.5 to 13dB, and a noise figure of 3.8 dB over 1-5 GHz frequencies. S11 is less than -8dB within the entire band of frequencies while the IIP3 is -1 dBm at 3 GHz. Compared with their traditional counterparts, the proposed LNA consumes less chip area 0.16 mm2 and presents better gain and noise figure performance.
