A new fully integrated receiver front-end operating concurrently over the two bands of 3.1-4.8 and 6.3-7.9 GHz of the UWB spectrum (3.1-10.6 GHz) has been developed using a 0.18-m CMOS process. The receiver front-end occupies a chip size of only 1.18 0.87 mm2 and exhibits conversion gains from 12.5-16.5 dB and 14.5-16 dB and RF return losses from 10 to 11 dB and 10.5 to 12 dB over the 3.1-4.8 GHz and 6.3-7.9 GHz bands, respectively. The measured input 1-dB compression points are -4.1 and -5.2 dBm at 4 and 6.5 GHz, respectively. The measured noise figure is from 7.5 to 12.5 dB across 3.1-7.9 GHz and less than 10 dB up to 7 GHz. The receiver front-end consumes about 42 mA of current from a 1.8 V power supply. 2009 Wiley Periodicals, Inc.
