Abstract

A 0.18μm CMOS low noise amplifier with broadband active input matching network in the frequency band of 0.6 - 6GHz covers GSM/DCS/WiMAX/WLAN applications for multi-standard system integration has been proposed. The broadband LNA achieves superior flat noise figure of 2.77dB with ± 0.09dB variation 0.6 - 6GHz and noise figure of 2.7dB ± 0.02dB within 0.6 - 4GHz by using active input matching network. The simulation results show that S21 of 20dB with a ±1.5dB variation and S12 of -65dB from 0.4 - 6GHz can be achieved. Power consumption is 19.5mW from a supply voltage of 1.8V.
