A 1GHz low power CMOS LNA

A 1.8 V 0.18 um CMOS LNA for GPS applications has been designed and under the supply voltage, the fully differential LNA has been simulated. It provides a series of good results in Noise figure, Linearity and Power dissipation. The LNA achieves a voltage gain of 24 dB, Noise figure of 1.7 dB and Power dissipation of 9 mW. Besides, the input third-order intercept (IIP
₃
) is 1.235 dBm and the input reflection coefficient (S
₁₁
) is -38 dB.
