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 presents the design of ultra-wideband low noise amplifier (UWB LNA). The proposed UWB LNA whose bandwidth extends from 2.5 GHz to 16 GHz is designed using a symmetric 3D RF integrated inductor. This UWB LNA has a gain of 11 ± 1.0 dB and a NF less than 3.3 dB. Good input and output impedance matching and good isolation are achieved over the operating frequency band. The proposed UWB LNA is driven from a 1.8 V supply. The UWB LNA is designed and simulated in standard TSMC 0.18 µm CMOS technology process.
