Abstract :
This paper analyzes the architecture of wideband low noise amplifier (LNA) for multi-band orthogonal frequency division multiplexing modulation (MB-OFDM) ultra-wideband (UWB) system. Noise matching and input impedance matching are compared among different LNA architectures. Power consumption and area for different kinds of LNA architectures are also compared through the figure of merit (FOM).
