Abstract

A high linearity differential low noise amplifier (LNA) is designed for WiMAX applications. A feed-forward correction circuit is applied to improve the linearity of LNA. The LNA achieves a power gain of 15.2 dB, a noise figure of 2.95 dB, an input referred third order intercept point of 3 dBm with power dissipation of 17.03 mW from a 1.8 V supply voltage. The chip is fabricated in TSMC 0.18-μm CMOS technology. The chip area occupies 1.13 x 0.99 mm 2.
