In this paper, the design of two low noise amplifiers proposed for WiMAX applications is presented. The two low noise amplifier topologies implemented are: cascoded common source amplifier, Shunt feedback amplifier. The amplifiers are implemented in a standard 180nm CMOS process and are operated with a 1-V supply voltage and 5.9GHz frequency; the cascoded LNA achieved the best performance with a simulated gain of 15.7dB and noise figure of 1.85dB. The Low noise amplifier has been simulated using cadence specter.
