A 2.4 Ghz Low Noise Amplifier in UMC 180 nm Technology

Pankaj Lodhi , Rajesh Khatri

The Low Noise Amplifier (LNA) is typically the starting stage of an RF receiver. Its is used in the communication system to provide enough gain with minimum possible noise at receiver end. The objective of this work is to find out an innovative design idea for LNA to obtain improved performance over the traditional design. The LNA Circuit designed here is for Wireless Local Area Network (WLAN) application i.e. 2.4 GHz. The main LNA constraints are Gain, Noise Figure (NF) and power consumption. In this paper the LNA is presented with Inductive degenerated topology using cascoded dual CMOS architecture for obtaining the improved LNA constraints. The LNA design is simulated in Cadence Virtuoso IC tool using 180nm technology. The results of the simulation shows that the gain is 12.35 dB, input return loss (S₁₁) of -6.842 dB, reverse isolation (S₁₂) of -32.9 dB, S₂₂ equals to -0.611 dB. It produces a Noise Figure (NF) of 0.281 dB and corresponding Noise Factor is 1.0068. This proposed LNA circuit operates at supply voltage of 1.8v.Keywords--Noise Figure, Cascoded LNA, Inductive degeneration, Radio frequency(RF)
