Abstract

A 2-6 GHz WiMAX Low Noise Amplifier (LNA) using active inductor as shunt peaking load in resistive feedback configuration is designed in 0.13-μm CMOS process. This low noise amplifier uses a single active inductor to achieve high gain and input matching which leads to a compact circuit. The simulations show a maximum power gain (S21) of 14.18dB, minimum noise figure (NF) of 2.44dB while the input return loss (S11) is less than -10dB over 2-6 GHz range. The total power consumption is 8.97mW with 1.2V power supply.
