Abstract: This paper presents the design and simulation of low-noise amplifier (LNA) with .18CMOS technology in 2.4GHz frequency addressed, the process HSPICE RF simulation software has been done. Using cascode structure leads to lower power consumption with higher voltage gain and power gain. Matching network was used in the design of this circuit has a very good improves on the parameter S11 and allows to have a good control on the real part of the impedance of circuit by appropriate selection of matching network in input and output. By right choosing of circuit elements in this structure can have an approllllojjpriate compromise among the circuit parameters like noise figure, gain, power and stability to reaching noise figure (NF), input reflection coefficient and low power consumption with high gain. In the 2.4GHz frequencyl with 1.8V supply voltage and 1.9 mW power consumption, the circuit parameters are: NF=1.21dB, Av=28.dB, S11=-29.25dB, S12=-35.49dB, S21=18.46dB
