Abstract :
This paper proposes a new low noise amplifier (LNA) circuit topology for WiMAX application. A feedback approach is applied to improve the linearity of LNA, and the power consumption of LNA can be reduced effectively by using the current reuse technique. Measured results of the proposed LNA achieve a noise figure of 3.6 dB and the third-intercept point (IIP3) of 0 dBm with power dissipation of only 4 mW from a 1.4 V supply voltage. The entire chip area occupies 0.55 mm × 0.96 mm in 0.18 μm CMOS process.
