Abstract :
This paper presents an ultra-wideband (UWB) 3.1~8.2-GHz low-noise amplifier design. Resistive shunt-feedback method is used to provide wideband input matching and low noise figure (NF). The cascade configuration is employed with the inductive source degeneration and an input three-section band-pass Chebyshev filter. The LNA operates at 1.5 Volt and consumes 16.2 mW. At 3.1~8.2-GHz, this LNA has NF of 3.6 dB, with input return loss of -12.155 dB, output return loss of -12.75 dB, and power gain of 11.43 dB. The circuit is designed with TSMC 0.18 mum single-poly-six-metal CMOS process
