This paper describes the design of a two stage 1V power supply SiGe Low Noise Amplifier operating at 5.25 GHa for 802.lla wireless LAN application. The achieved performance includes a gain of 17 ㏈, noise figure of 2.7㏈, reflection coefficient of 15 ㏈, IIP3 of -5 ㏈m, and 1-㏈ compression point of -14㏈m. The total power consumption of the circuit was 7 mW including 0.5mW for the bias circuit.
