This paper describes the design of a single-stage differential Low Noise Amplifier (LNA) for Ultra Wide Band(UWB) applications, implemented in state of the art Planar and FinFET 45nm CMOS technologies. A gm-boosted topology has been chosen and the LNA has been designed to work over the whole UWB band (3.1-10.6GHz), while driving a capacitive load. The simulations highlight that, at the present stage of the technology development, the Planar version of the LNA outperforms the FinFET one thanks to the superior cutoff frequency fT of Planar devices in the inversion region, achieving comparable Noise Figure and voltage gain, but consuming less power.
