Abstract :
A RF low noise amplifier used in Wireless Local Area Net system receiver, has been implemented in 0.25 μm CMOS technology. This paper analyzes low-noise amplifier (LNA) cascode topology, noise matching and input matching techniques. Design procedure and simulation results are presented with a 3.3 V supply and 2. 4 GHz frequency, the simulation result of S11 is -14 dB , S21 is 18 dB with 3 dB-BW of 300MHz and NF is about 1.8 dB. The 1 dB compression point is -19 dBm. The chip area is 0. 8 time 0. 6 mm2.
