A 1V low noise amplifier for WiMAX / UWB applications

摘要

A fully integrated dual-band LNA that can cover 2–11GHz and 3.1–10.6GHz 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 1V supply voltage.
