A 3 to 5GHz Common Source Low Noise Amplifier Using 180nm CMOS Technology for Wireless Systems
A low noise amplifier plays key role in overall performance of any RF receiver. This paper presents design of low noise amplifier by using RF CMOS technology for wireless receiver systems. The proposed low noise amplifier is implemented on TSMC RF CMOS 0.18um technology. The inductive source degeneration cascoded common source topology is used in the designed low noise amplifier. The designed low noise amplifier provides minimum Noise Figure (NFmin) less than 0.740dB, gain (S21) greater than 5.541dB, input return loss (S11) less than 3dB.
