A 1.2-v 2.4-GHz 0. 18 /spl mu/m CMOS low noise amplifier

A 1.2V 0.18 /spl mu/m CMOS LNA for Bluetooth applications has been designed and simulated. Under such a low supply voltage, the single-tone LNA has been simulated, it provides a series of good results in noise figure, linearity and power consumption. The LNA achieves a power gain (S21) of 15.16 dB, noise figure of 2.778 dB and power dissipation of 7.76 mW. Besides, the input third-order intercept (IIP3) is 1.188 dBm, the input 1 dB compression point is -8.73 dBm, and the reverse isolation (S12) is -30.6 dB.
