This paper include common gate (CG) LNA for ultra wideband (UWB) applications with CMOS trans conductance “gm” boosted. Noise distortion cancelled out by gm boosting technique and power minimization with he lp of current reuse technique. By CG - CS topology utilized to get more efficient parameters such as gain, stability, linearity and power dissipation. This design 0.13 um process CMOS technology which operated from 2 to 5 GHz with 1v supply. The common gate LNA design achieved forward gain (S21) of 15.50 db and reverse isolation (S12) in the range - 47.59 db to - 42.53 db and with input return loss (S11) and output return loss (S22) are - 18.50 db and - 11.42 db at 3.02 GHz and 5.01 GHz frequency range intensi vely Noise figure improved in this paper up to 2.93 db.
