Summary: | A 3.1-10.6 GHz ultra-wideband (UWB) low noise amplifier (LNA) utilizing a simple high-pass input matching network is proposed. The broadband matching and the flat gain are two important factors for the broadband circuits. Besides those factors, the minimal Noise Figure (NF), good linearity, and the lower power consumption are also desired. The LNA is designed in the standard 0.18μm CMOS technology. The input reflection coefficient S 11 and output reflection coefficient S 22 are less than -7.8dB and -11dB. It achieved maximum power gain 10 dB and the minimum noise figure is 1.75dB. It consumes 12mW from a 1.8-V supply voltage. The designed system demonstrated relatively suitable response in different temperature and Variation 10% supply voltage. |
