Optimal design of a low power UWB LNA for 5–10 GHz application

This paper introduces low power Ultra wideband LNA designed with lower supply voltage in 130nm CMOS RF technology for 5-10 GHz band application. The effect of parasitic and nonlinear relationship among performance parameters has been considered in the design process. Considering the maximum gain, low supply voltage has been used to reduce power consumption. Two designs have been proposed to distinguish the trade off among power, noise figure and linearity. Simulated results were compared with several published results on UWB LNA at simulation level.
