Abstract :
Ultra-wideband (UWB) is a promising new technology with great potential for short-range ultra-high-speed wireless communication systems. In this paper, a low noise amplifier (LNA) with broadband matching using a resonant circuit that has excellent gain flatness in the frequency range of 3 GHz to 6 GHz is designed for UWB applications. The TSMC 0.18 mum RF CMOS technology was used for simulation. Thus the final design does not require any off-chip components, being fully integrated. The LNA presented utilizes feedback and is composed of two cascode stages for the purpose of controlling both gain and noise. This paper describes the design approaches as well as the simulation results of the broadband LNA
