Abstract :
In this paper, a low noise amplifier suitable for wireless WCDMA systems is designed with AMS 0.35 μm CMOS process. A biasing circuit with temperature compensation is presented. The simulation result in Cadence shows that the LNA can achieve 12.7 dB power gain and 1.7 dB noise figure with 7 mW power consumption at 27°C. The gain and NF variations over -45°C to 85°C are less than 0.4 dB and 0.1 dB respectively
