This article presents the differential CMOS-LNA design for wireless receiver at the frequency of 3.4GHz. This differential provides less noise figure (NF), high gain and good reverse isolation as well as good stability. The designed LNA is simulated with a 180 nanometers CMOS process in cadence virtuoso tool and simulate the results by using SpectreRF simulator. This LNA exhibits a NF of 0.7dB, a high voltage gain of 28dB, and good reverse isolation (S12) of -70dB. It produces an input and output reflection coefficient (S11) of - 6.5dB and (S22) of -14dB, and it maintains good stability of Rollet factor Kf > 1, and also alternate stability factor B1f < 1, respectively.
