A Low-Cost and Low-Power CMOS Receiver Front-End for MB-OFDM Ultra-Wideband Systems

This paper presents an RF receiver front-end for MB-OFDM-based ultra-wideband (UWB) systems. The receiver occupies only 0.35 mm2 in a 0.18 mum CMOS process and consists of a low-noise amplifier, downconverter and a bandpass filter. There are no on-chip inductors and the receiver requires no off-chip matching components. The measured receiver gain is 21 dB, noise figure is less than 6.6 dB, input IIP3 is -5.6 dBm, and the receiver consumes 19.5 mA from a 2.3 V supply. The receiver covers all the MB-OFDM bands from 3.1 to 8 GHz.
