Abstract :
An ultra-wideband (UWB) 3 - 8 GHz low noise amplifier (LNA) using common-gate architecture and shunt-series feedback topology is presented in this paper. Two topologies of LNA are designed in a commercial 0.13 mum 1.2 V mixed CMOS technology. The common-gate LNA shows 9.5 to 12.8 dB power gain, 5.31 dB an average noise figure and 10.8 mW power consumption. A shunt-series feedback achieves 11.5 to 13.7 dB gain, 5.83 dB an average noise figure and 9.6 mW power consumption.
