Abstract :
In this paper, a 3GHz-10GHz ultra wideband (UWB) low noise amplifier (LNA) typology is proposed. The broadband matching and the flat gain are two important factors for the broadband circuits. Besides those factors, the minimal noise figure (NF), good linearity, and the lower power consumption are also desired. The common gate input stage with the 3rd order Butterworth filter configuration is used in the proposed LNA to achieve the broadband input matching. The flat gain of the LNA is achieved by the combination of the inductor peaking load and the shunt inductor insertion between the cascade stages of LNA. The LNA is designed in the standard 0.18mum CMOS technology. It achieved 14.5~15.3dB gain from 3GHz to 10GHz and 3.43dBm IIP3 in 5GHz, operates from 1.8V power supply, and dissipates 4.3mW without the output buffer
