Abstract :
A fully integrated dual-band LNA that can cover 2-11 GHz and 3.1-10.6 GHz for WiMAX and UWB receiver is proposed based on a current-reused technique with a simple high-pass input matching network and a resonator. Simulated results show that the proposed LNA has 11.5 to 12.2 dB power gain and 2.47 to 3.97 dB noise figure (NF), while consuming only 7.52 mW dc power with 1 V supply voltage.
