(English Abstract)
A CMOS LNA based on a single-stage cascode configuration is designed for MB-OFDM ultra-wide band(UWB) systems. Wideband(3.1GHz¡­4.9GHz) input matching is performed using a simple bandpass filter to minimize the chip size and the noise figure degradation. The simulation results using 0.18§­ CMOS process parameters show a power gain of 9.7dB, a 3dB band width of 2.1GHz¡­7.1GHz, a minimum NF of 2dB, an IIP3 of -2dBm. better than -11.8dB of input matching while occupying only 0.74§± of chip area. It consumes 25.8mW from a 1.8V supply.
