In this paper, a 2 -11 GHz WiMAX low simultaneously. noise amplifier (LNA) is designed and implemented in In order to simultaneously get better gain, noise and 0.18-,m CMOS process. The low noise amplifier good wideband by taking advantage from the utilizes a current-reused technique, a simple feedback current-reused configuration, a LNA based on the system and a high-pass input matching network. The current-reused configuration combining with a feedback LNA presents a maximum power gain of

The following section introduces frequency range of 2-11 GHz with a power dissipation the circuit topology and analysis. In the Section III, it of 14.3 mW under a 1.8V power supply. emphasizes on layout techniques for circuit operation at GHz frequency. Section IV presents the simulation results. Index Terms -Low noise amplifier (LNA), noise Section V makes a brief conclusion. figure (NF), WiMAX. Vdd Vdd
