This paper presents an Ultra-Wideband (UWB) 3-5 GHz Low Noise Amplifier (LNA) employing Chebyshev filter. The LNA has been designed using Cadence 0.18um CMOS technology. Proposed LNA achieves a minimum noise figure of 2.2dB, power gain of 9dB.The power consumption is 6.3mW from 1.8V power supply.
This paper is about Low noise amplifier topologies based on 0.18µm CMOS technology. A common source stage with inductive degeneration, cascode stage and folded cascode stage is designed, simulated and the performance has been analyzed. The LNA’s are designed in 5GHz. The LNA of cascode stage of noise figure (NF) 2.044dB and power gain 4.347 is achieved. The simulations are done in cadence virtuoso spectre RF.
