摘要：

This paper presents a wideband low noise amplifier(LNA) for multi-standard radio application. The low noise amplifier achieves wideband matching with the structure of differential common gate. Meanwhile, the low noise characteristic is achieved by noise canceling and capacitor cross-coupled. Fabricated in 0.18 mu m CMOS process, the LNA is designed to operate from 700MHz to 2.6GHz. As are shown in the results of simulation, when the LNA operates from 700MHz to 2.6GHz, the S11 is less than -10dB, the gain achieves 8.5 dB and the variation is within +/- 0.5dB. The noise figure is 2.2dB wih the supply voltage is 1.8v and the drain current is 8mA.
